Title: FitQuest AI – Complete Base44 Removal & Supabase Migration

I have a fitness application called FitQuest AI built using React/Vite. The project currently contains Base44 dependencies and I want to make it completely independent.
Requirements:
Remove ALL Base44 dependencies from the project.
Replace Base44 authentication with Supabase Auth.
Replace Base44 database functionality with Supabase Database.
Replace Base44 storage/file uploads with Supabase Storage.
Ensure all existing app features continue working correctly.
Configure environment variables properly.
Deploy the frontend on Vercel.
Connect the project to my Supabase account.
Ensure the application is fully independent and no longer relies on Base44 services.
Fix any issues caused during migration.
Deliver clean, documented source code.
Generate and provide:
Android APK
Android AAB (Google Play ready)
Technical Stack:
React
Vite
Supabase
Vercel
Expected Deliverables:
Fully migrated source code
Base44 completely removed
Working Supabase backend
Working Vercel deployment
APK file
AAB file
Deployment instructions
Please include:
Your experience with React/Vite and Supabase.
Similar migration projects completed.
Estimated completion time.
Fixed project cost.
The final result should be a fully functional application running entirely on Supabase and Vercel with no dependency on Base44.
