Full-Stack React Developer for SaaS Platform (Next.js / Supabase)
Phase 2 built directly on the strong foundation from Phase 1, and Maksym and his team once again delivered excellent results. The core focus this phase was consolidating and optimizing our platform's architecture, unifying the product, booking, and payment systems that had previously been fragmented across different service types into a single, streamlined structure. This wasn't glamorous work, but it was exactly the right call: it's made the platform significantly faster to build on, easier to maintain, and far less prone to the kind of edge-case bugs that come from duplicated logic.
Alongside that core optimization, the team also shipped a number of major new features, improving the Affiliate Program, a full review and moderation system, improved marketplace search, and a dedicated customer account experience, all while keeping the platform stable throughout.
As with Phase 1, communication stayed clear and consistent, and the team continued to bring a thoughtful, questioning approach rather than just executing tasks. We're confident the platform is in a stronger position technically than it's ever been, and we're looking forward to Phase 3.

Senior React.js / Next.js / Node.js / Supabase Developer
Max and his team did an excellent job during Phase 1 of our project and were a pleasure to work with throughout the engagement. They helped significantly improve the quality, scalability, maintainability, and overall effectiveness of our platform.
Communication was excellent from start to finish, and together we created a clear roadmap and task plan that kept the work organized and efficient. Beyond completing the assigned work, they asked thoughtful questions, challenged our assumptions, and encouraged us to think through business decisions that will ultimately improve the user experience.
Their proactive approach, technical expertise, and attention to detail added real value to the project. We still have additional phases ahead, and based on our experience so far, we look forward to continuing to work with Max and his team.

Senior React, Next.js, Supabase developer
Maksym and his team at Golden Team Soft agency were great to work with. They provided a robust plan that accounted for not just front end functionality, but also considerations for stability, scalability, performance, and security. The delivery of the work was smooth and on-time. If I need similar work in the future, I will work with them again.
The project was to take a prototype I had built in Lovable and take it to a production ready product with a Supabase backend. They set up dev, staging, and production environments to allow for stable future release cycles. They also improved the code base and made changes to allow for greater scalability, improve performance / applicaiton loading speed. They also added additional functionality that I was unable to build in Lovable.
