Full Stack Developer, Replit, Claude Code, Supabase, GitHUb

I am rebuilding my app. I need assistance with the backend. I need to connect Replit to Claude code, Git HUb, Supabase, eventually set up Stripe and Plaid. I have the PRD. I want to upload the PRD, have the repository in GitHub build the right folders needed for the build, and import the code to replit to build.
