Met projects milestones according to the schedule. 

Describe their project management. Did they deliver items on time? How did they respond to your needs?

What was your primary form of communication with CoreLine?

• Virtual Meeting
• Email or Messaging App

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

Their technical ownership — instead of writing code, they think about the whole system. They handled a sensitive compliance issues, set up proper audit logging and security tooling on AWS, and consistently approached infrastructure decisions (authentication, 2FA, deep-linking, data access patterns) with real security and compliance awareness rather than just shipping the fastest fix. Their documentation discipline is unusual for an agency — they produced thorough, well-organized technical and architecture documentation. Combination of great engineering, security-awareness, and documentation quality is what sets them apart.

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

There's not much to point to. If there is something to mention, it would be earlier and more proactive flagging of scope/effort estimates when requirements shifted.

What is the team composition?

We’ve worked with a lead designer and an account manager. 

How did you come to work with CoreLine?

Their team actually approached us several years ago, presenting themselves as a possible outsourcing partner. We kept in touch and reached out when we needed them. We chose them because they were flexible, worked to higher standards, and were priced better than local agencies.

I don’t know the exact amount, but we’ve invested under $5,000.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with CoreLine?

We needed help with web development.

They’re also helping us build a progressive web application, which will be used to onboard ships with unstable WiFi connections.

Currently, their team is working on fixing and implementing certain functionalities.

We’ve spent over $50,000.

What is the status of this engagement?

We started working together in March 2022, and our engagement is still ongoing.

CoreLine completes tasks in a professional manner.

How did CoreLine perform from a project management standpoint?

They deliver tasks on time. We communicate via Slack, Asana, and Google Meet; we’re in contact with them even during weekends.

What did you find most impressive about them?

I’m impressed by their responsiveness and time management skills. Also, they have skilled resources who can solve tasks promptly.

Are there any areas they could improve?

I can’t think of anything that CoreLine could improve on. They just need to continue doing what they’re doing.

BACKGROUND

Please describe your company and your position there.

I am an executive of a healthcare startup. We are a quality assurance platform with an overlay of remote patient monitoring for private pay home care agencies.

OPPORTUNITY / CHALLENGE

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

We are a healthcare startup and built our MVP 1.0 with developers in India. The system was built poorly. Coreline took over and has worked with us within our budget to get our platform running as smoothly as possible. We are now preparing to expand the platform to 1.5.

SOLUTION

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

We were referred to Coreline from one of our investors.

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

Coreline needed to familiarize themselves with the platform. We had introductory meetings with their team. Coreline took over from Upwork in India. Access information needed to be transferred. Coreline handled the transition smoothly and professionally. Dominik set us up with experienced developers that have been a pleasure to work with. Code needed to be rewritten in the Native language.

We created a system using Jira to keep track of old bugs and new bugs that needed attention. Our service with AWS needed to be reviewed and adjusted to insure we were HIPAA compliant. We have successfully completed our 1.0 MVP and are in a good place to begin designing and creating 1.5.

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

Dominik, Owner of Coreline oversees our Developement Team. We are currently working with 2 IT developers and 1 tester for both front end and backend.

RESULTS & FEEDBACK

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

Our platform is now running a lot faster and smoother. The Devs have worked on cleaning up all the outstanding bugs and blockers. Additionally, the Devs have been instrumental in adding the necessary HIPAA requirements to our platform ie. logs, access controls, integrity controls, backup schedule etc.

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

We meet bi-weekly, we communicate through Slack. The Devs are very responsive and timely to our questions. Since we are in a different time zone, they will respond if possible the same day otherwise, we generally will have a response the next day. We use Jira, Figma, Confluence, email to communicate information.

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

It has been a pleasure working with our Developers. They are a pleasure to deal with, very knowledgeable and patient. We consider them an integral part of our company team.

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

We had a sudden head developer change. He left the Company. We were not informed this was coming and totally surprised. However, Coreline had started a new developer a week or two beforehand and the assistant head was able to help with the transition.

BACKGROUND

Introduce your business and what you do there.

I’m the managing director at Insync Insurance Solutions Ltd. We’re an insurance business focused on SEM businesses across the UK that mainly trade online in niche areas.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with CoreLine?

We’ve been moving more of our products into an online solution. Initially, we brought them on to build a number of customer portals. They were responsible for the frontends of these solutions that integrated with our insurance backends.

SOLUTION

What was the scope of their involvement?

We began with one project and now have a monthly retainer with them. At first, they analyzed 1–2 of our products, identified the best UX for the frontend, and then developed it.

All their work has been web-based so far. This was based on their advice, as they thought insurance isn’t an industry that people desire mobile capabilities to engage with.

What is the team composition?

We deal with Dominic (CEO & Founder), and two of his full-stack development resources are also working with us.

How did you come to work with CoreLine?

We tendered the work to multiple people, and they responded. Based on their price and previous work, we thought they would provide the best value.

They showed enthusiasm for what we do and how they could add value. Not just inside the scope of the first project, but also within our entire business. The general view is that we see them as an extension of our business rather than a third-party contractor. We’re keen to develop future contacts with them.

How much have you invested with them?

We’ve spent around $250,000 with them so far.

What is the status of this engagement?

We’ve been working together since September 2019.

RESULTS & FEEDBACK

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

We work with another vendor who on our back-office. They’ve reviewed CoreLine's work and have come away very impressed. In terms of how we measure them internally, we look at cost savings, customer experience, and retention. Retention has gone up 6% since we launched the portal they developed.

How did CoreLine perform from a project management standpoint?

They immediately set up Slack channels and other communication pathways with clear project plans. If anything, they were the ones pushing us along, and not the other way around.

What did you find most impressive about them?

Their enthusiasm stands out. They get everything right the first time. They haven’t had to repeat any work. We previously had another vendor looking after our websites, but CoreLine has improved the speed on every site, taking our Google score from 70 to 96. They’ve moved us onto AWS in a seamless project. It was a high-risk strategy to move all the websites, but it went seamlessly.

Are there any areas they could improve?

I don’t think there’s been anything that they haven’t been able to find a solution for. If anything, I would suggest adding more regular strategic catchups, but that’s more up to me than it is to them. Rather than being strictly project-focused, we could work on high-level strategy together.

Do you have any advice for potential customers?

Have a firm brief and a lot of planning sessions before completely finalizing the project. They’ll have lots of good ideas to bring to the party.

BACKGROUND

Introduce your business and what you do there.

I’m the chief administrative officer (CAO) of a video-on-demand streaming service focused on content from Croatia and neighboring countries.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with CoreLine?

We went to them to develop a CMS.

SOLUTION

What was the scope of their involvement?

The project consisted of several phases, during which CoreLine developed several features to improve our platform and UX. They upgraded the frontend design and developed the backend CMS from scratch to fit our specific needs.

The CMS allows us to manage everything from registration to billing. We can also view statistics, such as viewing hours, to give us a better understanding of user behavior within the platform. They also developed a system that allows us to pull daily, monthly, and yearly reports on everything from platform usage and statistics to payment management.  

The third part of the CMS that CoreLine worked on allows us to manage the database that consists of the video files and the metadata. All the data is hosted securely on AWS.

Now we’re beta-testing the CMS and plan to continue working with CoreLine to develop mobile and smart TV apps.

What is the team composition?

CoreLine established a team of one designer, two developers, and a project manager.

How did you come to work with CoreLine?

We went through our address book and contacted developers we’d worked with before. A couple of them recommended Filip (Founder & CEO). They were well-experienced in the field, having worked on several similar projects in the past, so we had a meeting.

CoreLine met all of the requirements we needed we needed. They were a young team, but they were also experienced and efficient. Those were the key selling points for us.  

How much have you invested with them?

The cost so far is around €50,000 (approximately $60,000 USD).

What is the status of this engagement?

We started working with CoreLine in the fall of 2020 and we plan to expand our collaboration.

RESULTS & FEEDBACK

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

They’ve had a positive impact on our business so far. CoreLine completely understands our needs and makes suggestions to improve the system, then they implement those ideas in the most effective way. We’ve received more than what we’ve paid for.

We expect the product to provide a better UX to our customers. It also gives us a better overview of the use of our platform. We’ll be able to work more efficiently on the backend because our workflow is more organized. Now we can manage the whole platform autonomously.

Going forward, we plan to automate a lot of our other processes so we can focus on other areas of our business as well.

How did CoreLine perform from a project management standpoint?

We established a timeline at the beginning of the process, and CoreLine not only managed to deliver, but they were faster than expected at some stages.

They’re open to communication. We communicate through Google Meet and Slack. They’re always responsive — they always get back to us in a matter of minutes. When it comes to deadlines, they’ve met every single one that they predicted six months ago. As a result, we’re saving time with project development.

What did you find most impressive about them?

The CoreLine team is well-organized and structured. Each person involved in the project knows their field well. They’re clearly experts.  

Additionally, they work great as a team. When we go to their office for a meeting, we get a clear sense of their team atmosphere, and it’s great. Everyone seems to enjoy working there, which helps with client relationships. They’re very interested in the projects they’re working on.

Are there any areas they could improve?

I really have no complaints. CoreLine is very professional in executing the project, and I couldn’t say what they could do to improve.

Do you have any advice for future clients of theirs?

Someone looking to work with CoreLine shouldn’t hesitate to approach them. I would recommend new clients write to Filip, who’s always ready to find the best possible solution for your problem. Having direct communication with him can be the best way to assess them.

BACKGROUND

Introduce your business and what you do there.

I’m the COO of a clothing trade startup. 

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with CoreLine?

We were looking to partner with a development shop for the medium to long term.

SOLUTION

What was the scope of their involvement?

They rebuilt our iOS/Android app, which was quite messy, using React Native. They replicated the entire codebase and improved functions, such as messaging between users and push notifications. Then they cleaned things up, making the app more maintainable and scalable. 

What is the team composition?

There is a tech lead, project manager, senior software developer, a couple developers, and a designer. 

How did you come to work with CoreLine?

They were recommended by a different company. We spoke to them and decided they were the right partner for us because they were very upfront and seemed capable. 

How much have you invested with them?

We spent between $50,000–$99,999.

What is the status of this engagement?

We began working together in June 2020, and it’s ongoing.

RESULTS & FEEDBACK

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

They stepped up to the plate and worked very hard to get things done. 

How did CoreLine perform from a project management standpoint?

They meet deadlines relatively well. There were several delays because we underestimated the scope.

Communication has been quite smooth, and they are very available. I speak to most of the team daily.

What did you find most impressive about them?

They do a good job. They are more like a partner than just a vendor. 

Are there any areas they could improve?

No, not really. 

Do you have any advice for potential customers?

Clearly describe what you’re trying to achieve. They may be able to offer a better solution. Communication is key.

BACKGROUND

Introduce your business and what you do there.

Awaken Solutions Inc. is a web development firm based out of Montreal, Canada. I’m the owner and lead developer. There is one other developer who works with me.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with CoreLine?

I needed expertise with AWS and deploying a full-stack project that was going to be used by my client for their day-to-day CRM use. My client had grown out of their current CRM because they couldn’t integrate it with their investment software. The reliability and backups had to be extremely well done.

I also just needed more developers because the project had a tight timeline, so having my colleague and myself as the lead developer wasn’t enough to get the project done on time.

SOLUTION

What was the scope of their involvement?

The deliverable was a new CRM integrated with the client’s investment software. We built out a system that allows the client to CC or BCC a unique address, which then automatically logs all interactions with certain people within the CRM.

We also created a secure Google login and made sure that there was no way anyone else could access the CRM without an administrator’s permission. Finally, we built a complex reporting functionality with all of the possible filtering and searches in any field, whether it be the investment data or just generic contact data of all the contacts in the CRM.

What is the team composition?

I was the project manager, and CoreLine provided two developers and one designer. They were very professional.

How did you come to work with CoreLine?

I did a search on Clutch, and I looked at different companies and expertise. I reached out to them that way.

How much have you invested with them?

I’ve spent about $70,000.

What is the status of this engagement?

Our work together began in November 2019, and we finished the CRM project in May 2020. We’re working with them again for the same client, but on a new project.

RESULTS & FEEDBACK

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

Their level of expertise is excellent. They’ve been able to troubleshoot problems that arise, particularly with AWS, so their DevOps has been great. Anytime I hit a snag, I know I can ask one of them, and eventually someone’s going to figure it out. 

How did CoreLine perform from a project management standpoint?

CoreLine did very well. They were always available and able to meet deadlines. They provided good feedback and made suggestions, which led me to see that they could’ve easily managed the project as well. Because of the collaboration and my work with the client, I handled the actual project management. They were excellent.

What did you find most impressive about them?

Their professionalism sets them apart. They take themselves pretty seriously and are trying to achieve good things.

Are there any areas they could improve?

Right now, I can’t think of anything. It was a great experience.

Any advice for potential customers?

Have your own needs well lined up; they work very well with a good structure.
