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.
