I will build an ai powered full stack react and supabase web app
Sagi
About this gig
You need a working web app not a template. I build complete full-stack applications from scratch using React, TypeScript, and Supabase, deployed and ready to use.
I recently built Gymion a production-grade AI fitness platform with Google Gemini integration, video form analysis, offline-first PWA architecture, real-time sync, and multi-language RTL/LTR support. That's the level of engineering I bring to every project.
What's included in every package: React + TypeScript frontend Supabase auth and real-time database Responsive design, works on any device Deployed to Vercel, live from day one Full source code delivered
Need AI features, PWA, multi-language, or something more complex? Message me first and I'll send a custom offer sized to your project.
Before ordering, message me. Tell me what you're building and I'll confirm I can deliver it honestly.

Yes. Full source code is yours, no strings attached.
My project is bigger than your package — can you still help?

Do I need a Supabase or Vercel account?
Yes, but it's easy. I'll send you a simple 5-minute setup guide before we start. All accounts and code are yours from day one.
I'm not technical — will I understand what you build?
Yes. I explain everything in plain language and include a short walkthrough video on delivery. If you need AI features like Gemini or ChatGPT integration, just mention it and I'll handle the technical side completely.
