Hire a Supabase developer without the freelancer hunt

Supabase gives you a full Postgres database plus Auth, Storage, Edge Functions and Realtime, and apps can query the database straight from the browser. That speed comes with one rule that can't be skipped: row level security. With RLS enabled and sensible policies, a signed-in user can only read and change their own rows; without it, anyone holding your public anon key can read whole tables. Auditing and writing these policies, then testing them as different users, is the single most valuable job on most Supabase projects.

The service role key bypasses RLS entirely, so it belongs only in server code and Edge Functions, never in a mobile or web bundle. Work that needs it, such as handling Stripe webhooks, sending emails or calling third-party APIs with secret keys, moves into Edge Functions or your own backend. Auth is set up with the sign-in methods you need, redirect URLs for each environment, and custom SMTP, because Supabase's built-in email sender is rate-limited and meant for testing.

Schema changes are written as SQL migrations with the Supabase CLI and kept in your repository, so staging and production stay identical and changes can be reviewed. For apps leaving Firebase, the migration maps Firestore collections to relational tables, moves users across Auth, and rewrites security rules as RLS policies. Free projects pause after a period of inactivity, and backup and point-in-time recovery options depend on your plan, so the handover spells out what your tier provides.
