Please describe your company and your position there.

I am DCIO of an exciting new startup Platform for Health and Wellbeing, built on 8 health related pillars Emotional; Physical; Social; Intellectual; Sexual;Environmental; Financial; Spiritual.

For what projects/services did your company hire Jelvix, and what were your goals?

Jelvix have worked with Nexus through concept/design to build mobile prototypes for Android and iOS and are now commencing the product builds in readiness for an imminent launch.

How did you select this vendor and what were the deciding factors?

I was not involved in the selection process having only recently joined however- at my onboarding the Nexus team informed me that they had worked with several other partners who did not work out ; they were very pleased when they engaged Jelvix as they proved to be the professional team they required.

Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.

There are 2 themes B2H and B2B with eventual B2C. First Stage UX/UI Concept and Design for Android and iOS mobile Apps and the Backends - For design iterations using inVision/Monosnap - project run on AWS development platform Agile process managed through Jira, release CD/CI Github Build on AWS using various services "Backend:

1. Payment services

2. Post services iOS:

RxSwift – RxSwift is a library for composing asynchronous and event-based code by using observable sequences and functional style operators, allowing for parameterized execution via schedulers. RxSwift in its essence simplifies developing asynchronous programs by allowing code to react to new data and process it in a sequential and isolated manner.

Alamofire – Powerful network library for iOS and MacOS

Realm – Fast and powerful persistent object oriented database for storing data on the user's device. Helps to make the interface more responsive, because it allows you to display already saved data from previous use and in finished form and display them without waiting for a response from a network request.

At this point for this review, we are at the final stage of agreeing design freezes with Jelvix - so now moving into the build stage again using AWS platform with a target of implementing a production environment ready for B2H and B2B pilots.

How many people from the vendor's team worked with you, and what were their positions?

I have encountered 6 team members so far. I am working with a Senior Project Manager full time plus: iOS developer Android developer Backend developer Quality Assurance Engineer DevOps Engineer "

Can you share any measurable outcomes of the project or general feedback about the deliverables?

I joined Nexus beginning of August 2021 and was asked by the CEO to give my opinion on the work Jelvix had produced so far. I looked into what had been specified and what had been delivered and found it was of a very good quality- I asked a question of the Nexus team: what did they think of what Nexus had delivered and they all agreed it was very good quality.

Describe their project management style, including communication tools and timeliness.

The project management I have experienced since my start Aug 2021 has been very proactive - the style is collaborative and consultative and as with many startups they are flexible to the fluidity of changes in decisions.

What did you find most impressive or unique about this company?

I have run and worked development teams for over 25 years and for me as DCIO it is great to have a partner where they have access to an extensive range of technical and project skills with a background of diverse projects to help support an enterprise that is in its nascent form.

Are there any areas for improvement or something they could have done differently?

With only a few weeks experience of Jelvix I don't really have a view on this. There were some spelling mistakes and misinterpretations due to language

Please describe your company and your position there.

I am the CEO of a career management company specialised in digital technology to help people identify new careers.

For what projects/services did your company hire Jelvix, and what were your goals?

We hired Jelvix to undertake the development work on our mobile apps (iOS and Android) and web portal. Our goals were to create native mobile apps for career seekers and a bespoke web portal for businesses to post training and work opportunities.

How did you select Jelvix and what were the deciding factors?

I had previously worked with Jelvix in another company, when I approached them about this project they quickly grasped what we were aiming to do. Jelvix provided deep knowledge in the architecture and development work.

Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.

We had a kick off meeting to describe the aims of the technology, I had already created the wireframes and technical scope, Jelvix interpreted this very well. Once the scope was set we went through pricing and estimates on development times, these were then transferred in to sprints.

Once the sprints were set we moved on to development. There is always good communication and tracking, utilising Slack and PivotalTracker to help me understand where we were at all times. In addition our dedicated Project Manager created reporting documents and delivered these to me on a weekly basis.

The aim was to initially deliver two version 1 apps both native and a web portal to take to market, we did this successfully and swiftly moved on to growing and enhancing all platforms.

How many people from the vendor's team worked with you, and what were their positions?

• 1x iOS developer
• 1x Android Developer
• 1x Backend developer
• 1x Frontend Developer
• 1x Project Manager
• 1x Designer

Can you share any measurable outcomes of the project or general feedback about the deliverables?

Feedback has been very good, as well as being the UK's number 1 trending business app on Google Play, the quality of the work has helped us to attract new customers, partners and investors.

Describe their project management style, including communication tools and timelines.

Communication on a daily basis with project updates and questions, the developers never work on something they don't fully understand so the PM is a very important link to acquiring and interpreting client objectives.

There is always two way communication and regularly we are given recommendations on how certain functions could be better. The PM is happy to work on Slack, email and have calls when necessary.

What did you find most impressive or unique about this company?

Trust is a very important factor and I know that. Jelvix has gone above and beyond to make sure that they deliver on time and be flexible to our company's needs.

Are there any areas for improvement or something they could have done differently?

None that I can think of

Introduce your business and what you do there.

I’m the director and CEO of Websun Solutions UG. We create web apps, websites, and mobile apps.

What challenge were you trying to address with Jelvix?

There are some things we can’t do in-house, so we hired Jelvix for their expertise.

What was the scope of their involvement?

Jelvix provides development support for four different projects. Overall, they handle a lot of complicated development mostly dealing with music recognition algorithms. The projects involve AI, so the work is very difficult. There aren't many companies that have the skills to work on such projects.

What is the team composition?

I got in touch with their CEO at the beginning of the engagement. I also work with a dedicated project manager on a daily basis. Our feedback usually gets to the developers through our project manager, but we schedule direct calls if necessary.

They have many developers specialized in different programming languages, but we tend to work with the same developers on our projects.

How did you come to work with Jelvix?

I posted a job on Upwork that received several replies. We considered different companies but in the end, Jelvix seemed to be the only reliable company by far. Their profile was also suggested by Upwork's team because they're top-rated on the platform. From the beginning, we knew they were the perfect fit for our needs; and they still are.

What is the status of this engagement?                   

Our partnership began in April 2019, and it’s ongoing.

What evidence can you share that demonstrates the impact of the engagement?

Their work has been amazing. I love how proactive they are especially considering that some of the jobs require a lot of research and complicated algorithms because we’re a very niche space. Jelvix is always offering solutions, and it’s clear they’re invested in our projects.

The development process was perfect because they built the tools correctly, took the time to do their research, and proactively identified and resolved bugs. Their team also tried to improve the tools along the way so they could be faster.

At every stage and level, they’ve been great and quick to deliver. I used to develop websites myself so my background helps me know for a fact that they’re super good at development. It’s been a great experience so far.

How did Jelvix perform from a project management standpoint?

They use Trello and Slack internally, but my team doesn’t so we decided to exchange files on Google Drive instead. We preferred this, and our project manager accommodated it. Our teams communicate on a regular basis and through Skype. When I have a question, they always provide an answer. Our project manager is always available, even on the weekends.

Something interesting about them is that they give us business development help free of charge. For example, during the first project, Jelvix did AI research and simultaneously offered to give us feedback on our overall idea. They gave us suggestions on how to implement different features.

In the end, we decided to use the script for the website. This means users can pull a video or audio from YouTube, SoundCloud, an mp3 file, etc. and get the chords to play along. Jelvix gave us suggestions on how to implement different features. I didn’t expect them to provide free consulting.

What did you find most impressive about them?

I really like the fact that they’re so proactive. Usually, developers will just complete the bare minimum but Jelvix offers many different interesting approaches that address our needs. Because they work in so many coding languages, there are always solutions.

At the end of a recent project, we noticed the solution wouldn’t really work with our server. Their team did a quick change and fixed it just like that. If we need anything, they always deliver and it’s amazing. I don’t know many companies with their level of skills and capabilities.

Are there any areas they could improve?

Overall, I’m very happy. The only thing that could be better is having the possibility to add new milestones to perform updates and bug fixes once a project is finished. They have monthly plans instead but it's not exactly the same. For smaller projects, that's a big issue.

Do you have any advice for potential customers?

Everything has gone smoothly. They’re nice to work with so go ahead and engage with them.

Please describe your company and your position there.

I'm the CEO of a development agency working with startups and corporates on innovation and digital transformation projects

For what projects/services did your company hire Jelvix?

Working with a corporate client to create a customized CRM for them which has been rolled out to c. 80 parties now

What were your goals for this project?

• Make automation for Client’s billing
• Implement flexible & User-friendly reporting
• Integrate time & tasks tracking
• Keep the history of relationships with Partners

How did you select this vendor?

This company was recommended to me by a friend who has worked with them and I have since worked with them on a number of projects

Describe the project in detail.

Our web application is a Customer Relationship Management system where Companies can see their vendors or partners and keep all important notes about invoicing, contract, etc. and build reports upon request. Lots of automation and workflows were created to simplify user inputs

What was the team composition?

We have had a Project Manager as primary contact. Our team was composed of five developers, 1 UI/UX designer and 1 QA engineer

Can you share any outcomes from the project that demonstrate progress or success?

Very pleased with the outcome and having rolled out to c. 80 parties has really tested the platform and demonstrated product market fit!

How effective was the workflow between your team and theirs?

Their involvement added value to our project from the start. They are not shy about making their opinions known if it can help the project. Overall, despite being a remote team, it's been flexible and fast.

What did you find most impressive about this company?

This Team can provide you with effective solutions basing on your ideas - sometimes taking a fairly high-level concept that I throw at them and coming back with intelligent options. Very flexible and client-oriented company.

Are there any areas for improvement?

During the project, we had to revise user journey and initially we tried to do that through conversation only, which did not work that well so wasted a bit of time. We then decided to do mock ups to show the changes and went through things in detail through skype screenshare which really helped. So yes there were areas for improvement but that's been solved.

Project summary: 

Jelvix provided development services, working on expanding a B2B platform with APIs. They focused on developing the scope, adding edge cases and user stories, and integrating APIs.

Feedback summary: 

The team was focused, dedicated, and professional at all times, working hard to meet the deadline that was agreed. They produced a high-quality platform for excellent value for money, while working smoothly in an agile workflow.

BACKGROUND

Please describe your company and your position there.

I'm the founder and CEO of Appy Ventures, a tech partner to both startups and corporates that are looking to innovate. We have launched more than 60 apps, websites, and tech solutions.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Jelvix?

One of our insurance clients wanted to expand a B2B insurance platform with APIs. We needed a team to take the project from an idea to reality, providing detailed specification, coding, and project management.

What were your goals for this project?

To confidentially and securely build APIs to integrate systems with the platform. A lot of technology debt and stakeholder management was required, so Jelvix were chosen for their flexible approach.

SOLUTION

How did you select this vendor?

I've worked with more than 200 developers in the last four years, and I usually run small test projects to get a feel of working relationship. I was looking for a team that could grow with me and, after a lot of online research, I found Jelvix, who had also worked with a friend of mine. We ran a test project with them, and it was excellent, both in terms of communication and code quality.

Describe the project and the services they provided in detail.

I cannot go in details due to confidentiality, but it was a platform that connects the APIs of brokers to an insurance company, without the need for manual data entry in the process. We provided a top line scoping document which Jelvix built on after a workshop, adding edge cases and fleshing out the user stories. Once we had 100% clarity on the scope, we signed off on the work and the project was started properly.

What was the team composition?

I worked directly with a dedicated project manager, but we also had regular contact with the development team during daily 10-minute stand-up meetings. There were around six people on the project overall, with some scaling up and down for certain parts of the project. These transitions were all handled smoothly.

RESULTS & FEEDBACK

Can you share any information that demonstrates the impact that this project has had on your business?

Compared to UK-based developers, the cost is comfortably 50% less, but the quality is the same, if not higher. What mattered most to me was ownership of the project and the quality of the code delivered, which meant clear communication and hitting deadlines. They had to work weekends to finish on time, but they’d committed to a deadline and they hit it.

How was project management arranged and how effective was it?

This was a very important facet for me and was done well in an agile workflow. They used Jira and Slack, with standups on Skype. The language wasn’t an issue with the project manager, and though some of the developers were more comfortable in Ukrainian, it worked well overall and each team member made their opinions heard.

What did you find most impressive about this company?

They’re very focused on developing the right solution in the most efficient way, without being afraid of challenging my assumptions if they felt they could improve the end result.

Are there any areas for improvement?

There’s nothing that I can think of. I was very impressed and have found a reliable partner for the future.

Please describe your company and your position there.

I am the CEO and co-founder of a new funded startup aiming to disrupt the market with never before done app and web software.

For what projects/services did your company hire Jelvix?

We hired Jelvix for all iOS and Android app development, all our backend and database infrastructure, our custom content management system and a web based membership portal.

What were your goals for this project?

To produce a full-stack system on mobile and web that all work seamlessly together.

How did you select this vendor?

Having past experience with them on some major projects in my previous role I knew that the team at Jelvix had the communications skills, development expertise and drive to take on an ambitious project and make it work.

Describe the project and the services they provided in detail.

They helped to design and concept all backend and frontend systems. Once designed they swiftly moved on to the development of all systems concurrently (which is very hard to do). We were developing the backend infrastructure at the same time as the frontend web and app, which saved us a lot of time.

What was the team composition?

We had a core team of 5 developers all with their own expertise. There were times when they drafted in other developers with other skills to bolster the team and ensure success. Jelvix is very flexible to the needs of the project at certain times. There is never any compromise on quality. In addition to the devs, we have a dedicated project manager who ensures swift and accurate communication between us as a client and the developers directly.

Can you share any information that demonstrates the impact that this project has had on your business?

Jelvix has created an award-winning app for us. We are, in our nature, a very disruptive company and the team at Jelvix fully understood this and aligned themselves with what we are trying to achieve. As the project progressed they scrutinized the scope and worked out ways to do what we wanted much more effectively. They have the knowledge to take an idea and make it a reality. In addition, unlike other development companies, the team at Jelvix is dead against technical debt. At every opportunity, they create clean code that is flexible and scalable which is extremely important.

How was project management arranged and how effective was it?

We have a dedicated project manager who is available during working hours. He is extremely engaged in our project and knows it better than anyone. There is flexibility here too. As a company, we use Slack and PivotalTracker. Jelvix adopted these platforms to conform to our way of working in the company.

What did you find most impressive about this company?

Their dedication to the cause. They have taken on our project as their own and have delivered with real passion. There have been some really tricky parts to some of this build, things that had not been done before. Instead of shying away and doing the easy things they threw themselves into it and come up with solutions.

Are there any areas for improvement?

There are very little areas for improvement needed in my opinion. Clearly, they have refined their processes to be near-optimal.

Please describe your company and your position there.

I am the brand and marketing director at Auchan Retail, a top retailer in Ukraine.

For what projects/services did your company hire Jelvix?

We engaged Jelvix to create an e-commerce application on which customers could place pre-orders.

What were your goals for this project?

My company wanted to enhance customer service by reducing overcrowding in our physical stores during our busy periods. We hoped to build an online system where customers could place pre-orders for a streamlined in-store experience. A key challenge was building a top-notch, custom web platform under a very tight schedule.

How did you select this vendor?

My company sought a vendor that was well-versed in product development and cutting-edge technologies. We chose Jelvix based on their experience building products with aesthetic, innovative designs and reliable functionalities.

Describe the project and the services they provided in detail.

Jelvix built a web application for order management. They managed UI/UX design and front- and backend development.

What was the team composition?

My team engaged with a project manager, a backend PHP developer, a frontend AngularJS developer, and a UI/UX designer.

Can you share any information that demonstrates the impact that this project has had on your business?

Jelvix delivered a platform that not only met our requirements but exceeded our expectations. Customer feedback has been extremely positive.  

How was project management arranged and how effective was it?

Jelvix was committed to understanding our project requirements and providing optimal results. They demonstrated precise and coordinated teamwork and high proficiency in web development. The team was flexible and accommodating of changing circumstances. Communication was seamless.

What did you find most impressive about this company?

Jelvix was a wonderful IT partner that provided excellent customer support. They responded to challenges and delivered innovative solutions in a very timely fashion.

Are there any areas for improvement?

I definitely saw no areas for improvement. I highly recommend Jelvix to those who want to achieve ambitious goals and create sophisticated software products. They are a long-term partner.

Please describe your company and your position there.

I am the founder of Micswag LLC. Micswag is a mobile application that allows individuals to record vocals, collaborate with others to create and produce songs, and distribute songs on the go.

For what projects/services did your company hire Jelvix?

I hired Jelvix to design and develop a mobile app for iOS devices based on my ideas and initial mockups.

What were your goals for this project?

I aimed to provide a platform that allows individuals to record music while on the go. I wanted to develop an app to become the leading destination for audio and music recording.

How did you select this vendor?

After an unsuccessful partnership with a past vendor, I discovered Jelvix online. Their portfolio and client reviews stood out to me. I presented their team with my ideas and drawings, and the project managers immediately understood my vision. They eased my worries and had answers to all my questions, and I was convinced I could trust them with my vision.

Describe the project in detail.

Micswag allows users to listen to several options of instrumentals and beats, make a selection, and record their vocals. An artist can then collaborate with other users who can add vocals to the track or help produce it. Both users can distribute the song via social media and earn royalty compensation if their track is added to a listener's library.

What was the team composition?

I worked with a project manager that chose a backend developer and a graphic designer for my project.

Can you share any outcomes from the project that demonstrate progress or success?

Jelvix was able to design and develop the app exactly as it was intended, and launch it on the App Store. We just finished an update that allows video advertisements and additional methods of user compensation. Based on several completed and approved app updates, I'm confident that their professionalism can't be matched.

How effective was the workflow between your team and theirs?

The communication between myself and the Jelvix team was always easy. The project manager is very proficient in English.

What did you find most impressive about this company?

The most impressive trait about the Jelvix team is that you can't give them a task or idea too large. No matter how grand a vision you may have, they'll always have a solution or means to accomplish it.

Are there any areas for improvement?

Jelvix has gotten great reviews, happy clients, and more clients because of it, making them less and less available. This is good for them, and I'm confident they'll manage the growing pains well. I'm still finding my windows of opportunity with them.

Introduce your business and what you do there.

I’m the CEO of Switchback Health. We offer a home exercise application and software program for physical therapists, facilitating a smooth and effective way for professionals to create and share exercised with their patients.

What challenge were you trying to address with Jelvix?

We needed a vendor to develop our product. We were specifically looking to complete the first versions of the iOS app and web app.

What was the scope of their involvement?

Jelvix started providing full-service assistance from the very beginning of the project. Together, we refined our set of requirements for the UX/UI elements. From there, they guided us through and helped us with each stage of development—designing the apps, building the platforms, programming the backends, setting up databases, and several other tasks.

We completed an iOS version and a web-based version, and we have plans to build the Android version in the future. In the system’s current state, physical therapists can take videos or pictures of their patients at the time of treatment, then share those visuals to help guide their patients as they do their exercises at home. The physical therapists can also track patient progress, share messages via a chat function, and send alerts to remind patients to do their exercises.

What is the team composition?

We worked with a project manager, a designer, and a lead developer.

How did you come to work with Jelvix?

I heard about them through a friend.

How much have you invested with them?

We spent around $150,000 on this project.

What is the status of this engagement?

We worked with them from December 2016–September 2017.

What evidence can you share that demonstrates the impact of the engagement?

A huge challenge in the physical therapy community is encouraging patients to actually do their home exercises. The solution strengthens the relationship between doctors and patients and holds them accountable for their exercises in a more interactive way.

The apps themselves were very well developed. Since launching, over 1,500 patients have successfully used the solution, and we continue to receive praise for its quality and performance. The positive reaction speaks to Jelvix’s development work.

How did Jelvix perform from a project management standpoint?

We communicated during in-person meetings, over the phone, and through email exchanges. Overall, their management and collaborative skills were excellent.

What did you find most impressive about them?

This is my first time working on a project, so I don’t have much to compare it to. Based on my experience, I’m most happy with the ratio of cost to quality that Jelvix offers. They’re a team of skilled developers and programmers, and their prices are competitive compared to others in the market.

Are there any areas they could improve?

I can’t name any major areas of weakness for Jelvix. Given the regional differences, communication was a bit of a challenge, but we’re very happy overall.

Please describe your company and your position there.

VocalReferences is SaaS platform dedicated to capturing, displaying, and optimizing customer feedback. I’m one of the co-founders.

For what projects/services did your company hire Jelvix?

We needed a team to take our project from an idea to reality. That included providing interface design, a detailed specification, and coding. We hired Jelvix to develop the application to be launched on iOS and Android.

What were your goals for this project?

To create a fully-functional iOS and Android app. We had strict deadlines, so the project needed to be completed within one year.

How did you select this vendor?

We used to cooperate with a company that used Jelvix's services. We looked for partners with the end-to-end capabilities to make our application come to life. We considered hiring in-house resources but concluded that Jelvix would be the best choice for creating a market-ready application in under one year.

Describe the project in detail.

It’s a mobile social application that captures and displays video and audio testimonials. Users can review them, save them as favorites, and use tags for simplifying search option. They can also share content from the app to different websites.

What was the team composition?

I worked directly with a dedicated project manager on their side. They have a massive team of developers and QAs that work with us.

Can you share any outcomes from the project that demonstrate progress or success?

The application became live and revenue-generating within one year. The thing that mattered most to me was the timeline. We gave deadlines as to when the app must be released for testing, and they never missed a single one. They’re the first company I’ve worked with that always delivers results according to the promised schedule.

How effective was the workflow between your team and theirs?

They were great, and function as if they are our employees. We had regular meetings in which they informed me about their progress. Most of our communication was done via project management tools and weekly phone calls.

We gave them a lot of feedback in a short period of time, making tweaks, upgrades, and changes to the development schedule. They were accommodating and flexible at all times.

What did you find most impressive about this company?

They always responded to us within a few minutes, which I found impressive. They’re the most communicative team I’ve ever met.

Are there any areas for improvement?

They’ve done an exciting job. Working with them was one of the best business decisions I’ve made.

Please describe your company and your position there.

I am the CTO of VisiQuate, a data analytics firm.

For what projects/services did your company hire Jelvix?

I hired Jelvix to take over the development process of a client’s mobile application from another vendor.

What were your goals for this project?

We tasked Jelvix with addressing the significant performance issues within the app.

How did you select this vendor?

A personal connection recommended Jelvix. They were described as a reliable partner with experienced engineers.

Can you go into detail about the services they provided and the scope of the project?

After taking the lead on the development process, Jelvix performed architecture and code reviews and worked with our client to resolve the existing problems. They improved the overall user experience by deleting those bugs and introducing new features.

The app was constructed for iOS and Android platforms. It serves as a social app that allows parents and children to capture and share photos and videos at sporting events.

What was the team composition?

We worked with an account manager, an iOS developer, and an Android developer.

Can you share any information that demonstrates the impact that this project has had on your business?

As a result of that engagement, the apps went through a series of code changes, optimizations, and redesigns. The final version was a satisfactory MVP.

How was project management arranged and how effective was it?

We appreciated their follow-up process and their approach to project management. The agile methodology used was appropriate for this type of project.

What did you find most impressive about this company?

The Jelvix engineers displayed a team effort to produce quality code and deliver a reliable end product. They were focused on meeting the business goal and providing the app on time and within budget.

Are there any areas where they can improve?

I cannot pinpoint anything that needs improvement.
