Senior Flutter + FastAPI Full Stack Developer Needed for Premium Video Dating App (Long-Term)

Senior Flutter + FastAPI Full Stack Developer Needed for Premium Video Dating App (Long-Term)

Project Overview

I'm building LunaConnect, a premium real-time social entertainment platform similar to Chamet, MICO, Bigo Live, LivU, and Tumile—but with its own unique UI, business logic, and architecture. The project overview documentation has already been started.

The project is already well underway with thousands of hours invested. I'm looking for an experienced developer to continue, improve, and complete the project—not build it from scratch.

This is a long-term opportunity for the right person.
