transcript.
BACKGROUND
Introduce your business and what you do there.
I’m the CEO of Eric Roberts Fitness.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with Onix-Systems?
I wanted to take my existing WordPress site and create a mobile web app.
SOLUTION
What was the scope of their involvement?
Onix-Systems has built a mobile web app from scratch using Vue.js. The team has created user personas, designed the UI/UX, and developed the app. They’ve used Figma for the design components, which include a new logo, color scheme, and other elements.
Users can access videos and complete workouts through the app. They can also log their reps, sets, body weight, and other data points.
What is the team composition?
I’ve worked with three people: Andriy (Project Manager), Maryna (Project Manager), and Alla (Account Manager).
How did you come to work with Onix-Systems?
I found them on Upwork and looked at their reviews. After scheduling a call with their project manager, we decided to move forward with the partnership.
How much have you invested with them?
We’ve spent around $80,000.
What is the status of this engagement?
We started working together in July 2022 and launched the web app in January 2023. Our partnership is ongoing.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
Since launching the app, we’ve seen 330 user sign-ups, which is great. I’m super happy with the work Onix-Systems has delivered.

Onix-Systems has been top-notch across the board. They use Miro to manage the project, and everything is in line with my expectations. We communicate via email, Slack, and Google Meet.
What did you find most impressive about them?
I’ve been most impressed by their level of communication and timelines. They communicate effectively and are outstanding at completing tasks quickly.
Are there any areas they could improve?
Our budget has increased, but that’s my fault because I've added items to the project scope.
Do you have any advice for potential customers?
I recommend engaging Onix-Systems and asking questions. They’re super responsive and willing to help you however they can.

Onix-Systems is the development partner of a fintech startup. They’ve helped them design and develop their banking app and admin portal using Java, Sprint Boot, Flutter, and Vue.js as the main technologies.
Onix-Systems has become an extension of the client’s team, bringing their expertise to the table to bring the product to market. The team is very communicative and adaptive, and their English level is outstanding. Additionally, their QA process is impressive, allowing them to deliver quality work.
A Clutch analyst personally interviewed this
client over the phone. Below is an edited
transcript.
BACKGROUND
Introduce your business and what you do there.
I’m the co-founder, COO, and CPO of a fintech startup company.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with Onix-Systems?
We didn’t have the technical expertise in-house, so we were looking for a development team that could act as an extension of our company.
SOLUTION
What was the scope of their involvement?
Onix-Systems handles our application development work. They use Java and Sprint Boot for backend development, as well as Flutter and various third-party integrations for frontend development. Additionally, they’ve helped us develop a web-based administration console using Vue.js. Initially, Onix-Systems brought one of their experts to help us define the solution’s specifications, prioritize the functionalities we needed to implement, and validate our concept.
Ours is a youth banking app, so the main features of our app are on the backend. It’s fully integrated with a banking-as-a-service provider who helps us with our card processing and financial transactions. This app is available for Android and iOS.
The app is very similar to other neobanking apps, allowing clients to monitor their transactions, balances, and cards. It also lets them control their cards by setting restrictions or allowing them to block them. Within it, we’ve also included a referral program where people earn money for referring their friends.
What is the team composition?
We currently work with two full-time developers, a QA engineer, and a UI/UX designer. Still, Onix-Systems scales their team up and down as needed. In the past, we’ve worked with up to three frontend developers and three backend developers, and we’ve brought Vue.js developers to help us with the administration console as required.
How did you come to work with Onix-Systems?
I found them on Upwork. Initially, I wanted to build a very small app to test the market, and I was having issues finding a partner who could code in Java. Thus, they reached out to me and told me that they could do the front- and backend development work for me, which was great because I didn’t want to have two separate teams. After they completed the app, we continued working with them.
How much have you invested with them?
We’ve spent around $192,000 so far.
What is the status of this engagement?
We started working together in October 2021, and our engagement is ongoing.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
We don’t have quantitative metrics regarding Onix-Systems’ work because they simply work as an extension of our team. Still, the level of expertise they’ve brought to the table to support our development efforts is the main success factor for us to continue working together. Our app recently went into the VISA payment system, which was our goal.
How did Onix-Systems perform from a project management standpoint?
Onix-Systems has performed very well, and their price is very competitive. Even though they’re based in Ukraine, their English level is amazing. Additionally, their QA is excellent, so they’ve fixed every issue before launching the app. The project manager from their end is also great; she stays on top of everything and is very organized.
I’m very involved in the project, so we have daily meetings on Google Meet — as I said, they act like part of our team. They use Jira for project management, and we use Slack as our main communication tool. Still, we can jump on an additional Google Meet call if we need to talk to them.
What did you find most impressive about them?
Everything Onix-Systems does is impressive, but their English level is their best asset. Additionally, they’re very communicative and adaptive to change, and they always explain things to me that I don’t understand.
Are there any areas they could improve?
I can’t think of anything they could improve on.
Do you have any advice for potential customers?
I highly recommend working with them.

E-Learning App Development for Software Development Firm
Onix-Systems developed an e-learning app for a software development firm, incorporating data analytics, a backend for user registration, and web-based access.
Onix-Systems has a very flexible workflow that ensured clear communication. They provide great value to the client's business as they continue to add more content and mini-games into the app. The client looks forward to launching their marketing campaigns.
The client submitted this review online.
BACKGROUND
Please describe your company and your position there.
I am the CEO of a Software development company headquartered in Connecticut.
OPPORTUNITY / CHALLENGE
For what projects/services did your company hire Onix-Systems, and what were your goals?
We wanted to create an educational app to help kids learn reading comprehension, for a client/investor interested in this space. We needed it to be fun and engaging, with 3D environments as well as some 2D graphics, and to use speech recognition and track the child's progress.
SOLUTION
How did you select this vendor and what were the deciding factors?
We searched online for developers and spoke with several. We chose this developer for the ability to implement our ideas as well as supply ideas and solutions of their own. They also had great communication skills, flexibility, and a wide array of experience with relevant projects.
Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.
We provided the team with a detailed design document at first, and visual designs, and they implemented what we needed in Unity. As we progressed, we had additional features requests and more and more complex versions, and the team continued to deliver. They also became more and more involved in the process of designing the details of the app functionality, as they were providing great ideas and solutions themselves. They also incorporated data analytics, while maintaining necessary user privacy for kids. They developed a backend where user registration can be securely stored, and also a database where educational content can be stored and edited and displayed in the game on the fly. They also created web access for our clients to access that. We eventually moved the visual design to their team as well, since they showed they did great work on that end too and it made sense to consolidate.
How many resources from the vendor's team worked with you, and what were their positions?
We had a project manager at all times, as well as ongoing contact with all developers working on the project.
RESULTS & FEEDBACK
Can you share any measurable outcomes of the project or general feedback about the deliverables?
Our app MVP was delivered at high quality to the clients/investors and made them very happy. They continued to fund additional development due to the great results and great value the team provided. We are continuing to work with them to add more content and mini-games to our educational app. It has already been soft launched on the app store, and a bigger launch with more marketing efforts behind it will be coming soon, once we add some more content to the app and get some more feedback from our current testers.
Describe their project management style, including communication tools and timeliness.
The project management was very flexible, with clear communication and a willingness to meet client's needs. We had easy communication via tools like skype and Trello, both with the project managers and with the developers.
What did you find most impressive or unique about this company?
They do great app development work, and they bring their own ideas and suggestions to the table. Both the project managers and the developers are very forthcoming with ideas, realistic timelines and suggestions. They are true partners who take initiative and clearly care about the project.
Are there any areas for improvement or something they could have done differently?
In one or two cases, it might have been useful to know further ahead of time when a developer is going on vacation or becoming briefly unavailable due to other projects. But having said that, I think this is understandable too, given that our projects often ended up growing in scope and timeline. And to their credit, any time we were in a pinch, they offered additional developers who could help. So we're very pleased.

Onix-Systems is helping a SaaS firm develop an iOS and Android mobile app based on the codes, app designs, and front- and backend logic they provided. The app features camera integration and third-party APIs.
Onix-Systems has launched a fully functional app on App Store and Google Play Store within four months. A week after the app's launch, the client has achieved over 100 downloads and an aggregate five-star rating. Moreover, the client praises the vendor's development capabilities and knowledge.
The client submitted this review online.
BACKGROUND
Please describe your company and your position there.
I am a Co-Founder of a SaaS company focused on digital marketing services. The mobile app platform allows for the personalized creation, optimization and analytics of Google, Facebook and Instagram ads.
OPPORTUNITY / CHALLENGE
For what projects/services did your company hire Onix-Systems, and what were your goals?
We wanted to complete the development of a mobile app for users to obtain our digital marketing services. While we had very initial code, designs and project vision, our goal with Onix was to develop a fully functioning mobile app for users and admin panel for internal use.
SOLUTION
How did you select this vendor and what were the deciding factors?
We used the company Aloa to find, interview and hire Onix. Understanding Aloa's vetting process, meeting with the Onix team to gauge their understanding of the defined project, and discussing estimates with the team ultimately led to us confidently starting the partnership with Onix.
Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.
We had a number of introductory and discovery meetings early on to discuss our goals, objectives and deadlines with the project. We provided the team with early code, app designs, app logic and backend logic. Within 1 week, the team delivered an already much-improved test version of the iOS and Android apps.
Throughout the project, the team provided detailed and consistent updates on app progress and delivered an approved and launched app within the App and Google Play Stores. The app features and builds include push notifications, camera integration, support desk, and a number of third-party APIs. We continue to work with the team across app development and feature builds.
How many resources from the vendor's team worked with you, and what were their positions?
We were assigned:
1 project manager
4 full-time developers
1 QA
At times during our project, resources have varied to include part time and DevOps positions.
RESULTS & FEEDBACK
Can you share any measurable outcomes of the project or general feedback about the deliverables?
Within 4 months, a fully functioning approved app was launched in the App Store and Google Play Store. Within the first week of launch, the app saw over 100 downloads, and an aggregate 5-Star rating.
Describe their project management style, including communication tools and timeliness.
The project manager has been easy, responsive and organized to communicate with. While status meetings occur throughout the week, any messages or emails outside of meetings are clear and have quick response times.
What did you find most impressive or unique about this company?
The team's capabilities and knowledge in the mobile app space have been incredibly impressive. Additionally, their clear communication and quick response have resulted in efficient project management and completion.
Are there any areas for improvement or something they could have done differently?
An area we've improved together throughout the project is centralizing communication.

A VR firm has hired Onix-Systems for their dedicated VR and AR development resources. They provide customer projects for Onix-Systems to complete, split into tasks that are then executed in several revisions.
Onix-Systems' deliverables match the client's customers' goals within the first few revisions. Their high-quality products are always QA'd and have no technical issues. The partners communicate through Zoho Cliq, and Onix-Systems is very responsive to the client's messages and revision requests.
The client submitted this review online.
BACKGROUND
Please describe your company and your position there.
I manage a web & VR development company. My work includes selecting contractors, writing technical specifications, project management and occasional programming.
OPPORTUNITY / CHALLENGE
For what projects/services did your company hire Onix-Systems, and what were your goals?
We outsource most of our VR/AR/Unity work to them as they have a dedicated team of very proficient developers. Hiring was a challenge for us in Canada and Onix proved to be a reliable and effective partner.
SOLUTION
How did you select this vendor and what were the deciding factors?
We needed a partner to communicate openly and that would reliably deliver quality work. Communications has always been smooth with managers at Onix and without a doubt a better experience than most of our previous contractors.
Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.
The client usually explains in non-technical terms what they require. I then translate it into something that is mostly ready to be given to developers directly. Then Onix usually split the tasks into several revisions. They send me regular revisions and either jump on the next features or implement my feedback or the client's feedback.
How many people from the vendor's team worked with you, and what were their positions?
I worked with 2 managers and 3 developers. Usually, in voice meetings, someone would share their screen and we would discuss openly, while managers are taking notes.
RESULTS & FEEDBACK
Can you share any measurable outcomes of the project or general feedback about the deliverables?
As our projects are mostly about delivering interesting features in highly unique projects, it is hard to provide any measurable outcomes. However, I can say Onix always delivers what is asked or is very close to it within the first revision. They always deliver quality work with no glaring issues or lack of QA.
Describe their project management style, including communication tools and timeliness.
We mostly communicate through Zoho Cliq (my choice). They are timely to answer and whenever there is a pause in communication, it's always waiting on me. We mostly communicate via chat and revision documents, but once a while and whenever I ask, we do voice meetings, usually to share screen.
What did you find most impressive or unique about this company?
They always have an elegant way of achieving the desired results. Over the projects, some more challenging stuff was required and they delivered.
Are there any areas for improvement or something they could have done differently?
The developers are for the most part not very fluent in spoken English. Written communication with developers is perfectly fine and managers who handle most of the communication are very fluent but in screen share meetings, there have been a few occasion when developers asked questions to clarify what was needed and sometimes it felt like language was getting in the way.
