Full Stack Developer React Node (Full-Stack Node.js, SaaS)
Andriy and his team did an outstanding job on our Full-Stack Node.js + React/Next.js application. As a node.js developer and full stack nodejs team, they quickly understood the architecture, implemented new features end-to-end, and improved our existing codebase without regressions. Their API design and integrations (auth, analytics, etc.) were clean, well-structured, and thoughtfully optimized for performance and security. Communication was excellent, with clear PRs, tests, and concise documentation. We highly recommend Andriy and his team for any production full stack node.js react work.
