I need a seasoned full-stack developer who lives and breathes Supabase to architect and maintain the entire backend for my cross-platform mobile application (iOS & Android). Nothing has been created yet on the data side, so you’ll start with a clean slate: design the PostgreSQL schema, wire up Supabase Auth, configure Row-Level Security, and expose real-time endpoints that plug straight into the mobile client. What must be in place when we wrap up: • A well-structured database schema created from scratch and documented. • Secure user authentication through Supabase Auth, ready for email/password and popular OAuth providers. • Real-time data subscriptions working seamlessly with the app, using Supabase’s Realtime service or Edge Functions where appropriate. • All tables protected with role-based access policies to keep user data safe. • Clear integration guides or sample calls so my mobile team can hook in immediately. • A brief hand-off session plus ongoing availability for future iterations if things go well. I’m happy to iterate quickly over Slack or GitHub, and I value clean code, sensible naming, and performance-minded SQL. If you’ve already launched projects on Supabase and can show production examples, you’ll jump to the front of the line.
