App Development for Strategic Design Company
"They are true artisans, keen to craft a great product, highly responsive, and very proactive."
the reviewer
the review
The client submitted this review online.
Please describe your company and your position there.
I am the CEO of a Strategic Design Company
For what projects/services did your company hire Prime Holding JSC?
Our client needed to create a proof of concept for their mobile banking application using cutting edge technologies. We engage Prime to explore with us a flutter proof of concept to demonstrate how flutter could support in delivering not only a beautiful interface but also enhance the customer experience.
What were your goals for this project?
Demonstrate that Flutter is a real alternative to the current FE technology
How did you select this vendor?
We were referred to Prime from a client of theirs in the UAE in 2019. We found them to be incredibly proactive and experienced in flutter.
Describe the project in detail.
We provided Prime with 20 screens (customer journey) for an existing customer, as well as animations. Over three weeks working in agile and using cloud-based tools we were able to deliver in a very tight timeline. We were also required to integrate the app into a newly deployed sandbox to show realtime (anonymized) client data.
What was the team composition?
We worked with the head of delivery and 3 flutter developers.
Can you share any outcomes from the project that demonstrate progress or success?
The client was super happy with the POC, from the CEO to direct the client. The app clearly demonstrated that flutter could indeed raise the bar for mobile banking and we are now exploring how to move forward with the entire mobile banking app.
How effective was the workflow between your team and theirs?
Jira formed the backbone of the workflow between ourselves and prime and was very effective.
What did you find most impressive about this company?
The guys are amazing. They are true artisans, keen to craft a great product, highly responsive, and very proactive.
Are there any areas for improvement?
None that are apparent.

Web Dev & Infrastructure Migration for E-Learning Site
"They're a true partner, not just a vendor."
the reviewer
the review
The client submitted this review online.
Please describe your company and your position there.
Jigsaw Interactive is a virtual learning and collaboration tool used by Corporations, Colleges, and K-12 schools of all types and sizes. I am the Chief Of Innovation which encapsulates both CIO and Software Development.
For what projects/services did your company hire Prime Holding JSC?
We originally took over this project from another team who had reached the limit of their technical expertise. The product was very unstable, not cloud-based, not scalable, no automated code delivery, running on fixed Microsoft servers and used Flash. We needed a team who was cloud-first who had experience creating web-based applications using streaming audio, video, voice, desktop-sharing using HTML5/WebRTC in a real-time multi-user collaborative environment. The infrastructure needed to be changed from server-based to Docker/Kubernetes. We also needed them to be fluent in database technologies and traditional web development as well. We also needed full Mobile capabilities.
What were your goals for this project?
Move from hardware/server-based to cloud-based technology stack. Move from Flash to HTML5/WebRTC using Node.js for the client application. Move from server-based to use Dockerized containers in a custom Kubernetes environment. Implement data warehousing and end-user dashboards. Make the stack scalable while also reducing environment costs. Have a long-term technology partner. Have a stable product/platform.
How did you select this vendor?
We tried many different vendors from several places prior to choosing Prime. They each had positive aspects, but none had the scope of talent, the technical approach, nor the characteristics of a long-term partner. Prime ticked all of our checkboxes and were very straightforward with high integrity throughout our process.
Describe the project and the services they provided in detail.
We have a team that we have broken down into functional areas: - Infrastructure (all cloud-based server management, Kubernetes/Docker environments, networking, load-balancing, edge-computing, CI/CD management, and security) - Conferencing (HTML5/WebRTC client components, Angular/Node.js coding, mobile implementation, and media server implementation) - Backend (.NET/C# coding, backend/admin client development, database management, e-mail management, and API/middleware) - QA (automated and manual product testing, ticket-testing, and load-testing) - PM (developer management, project planning, resource allocation, ticketing system management) - Design UI/UX (creating standards, design, UI creation, UX refactoring, proof-of-concepts)
What was the team composition?
The size of the team varies according to the type of work being done, the skillsets needed and the delivery schedules. We currently have around 30 members on the team. Some members of the team have been with us for the entire 10-years so far. We have team members with a wide variety of skillsets, including: Infrastructure, Networking, DevOps, Backend Development (C++, C#), Frontend Development (C++, Node.js), API/Middleware, Mobile, Database design, UI/UX, media servers, Quality Assurance, and Project Mangement.
Can you share any information that demonstrates the impact that this project has had on your business?
This project IS our business.
How was project management arranged and how effective was it?
We use a variety of PM tools including in-house staff management software Primer, Jira, Assembla, GitHub, Slack, and our own collaboration tool, Jigsaw Interactive. We have never experienced language barriers because everyone on the team is fluent in English. The 7-hour time difference is factored into our release schedules (usually the time difference works in favor of our timelines).
What did you find most impressive about this company?
The highest level of Integrity in every facet of business. They're a true partner, not just a vendor. A wide variety of skills and strengths. Essentially, we have never had a situation where our team could not do what was needed within the timeframe that was needed. They have pulled off minor and major miracles for us many times.
Are there any areas for improvement?
It would be in any Customer's best interest to treat Prime Holding as a partner with open and clear communication. Allow for a FULL team setup with Prime (including PM, QA, and Design UI/UX) to make the most out of the time difference. Most importantly, empower the team to make their own decisions. If you treat them as a simple vendor that just gets plugged into one small aspect of the project, you are missing out on your team's real potential. I also encourage an in-person visit to meet your team. I usually make bi-yearly visits where I get to be face-to-face with the team and this time is valuable for understanding personalities and getting the most out of our relationship.
