SaaS Platform · React + Fastify · PostgreSQL

About the Project

We’re building a sophisticated AI-powered matching and analytics platform that uses multi-dimensional profiling and advanced algorithms to optimize decision-making.

The product has a validated prototype and real traction. We’re now moving into production hardening and scale, and we’re looking for a senior developer to take ownership of the backend architecture while actively evolving the frontend.
