Full Stack Developer for SaaS MVP

Looking for an experienced full stack developer to help get our SaaS MVP up and running. We've built the foundation using React for the frontend and C# ASP.NET Core for the backend, but need someone skilled in both to polish things up and get us launch-ready. The app is pretty much there but needs some debugging, optimization, and final touches. You'll be working with our existing codebase to fix issues, improve performance, and make sure everything integrates smoothly. We're open to working with individual developers, small teams, or agencies - whatever gets the job done efficiently. Need someone who can jump in quickly and understand what we've built so far. Timeline is flexible but hoping to wrap this up in the next 2-3 months.
