Supabase App Finalization

We're looking for a freelancer with strong, hands-on experience building apps in Lovable to help us finalize an existing app built on Lovable with Supabase edge functions — fixing bugs, hardening backend security (removing hardcoded secrets, migrating to Lovable's secrets manager), cleaning up domain/routing configuration, and implementing SMS verification and messaging (A2P 10DLC campaigns, phone provisioning, opt-in flows, verification codes). You should have proven Lovable project experience (portfolio links appreciated), be comfortable with Supabase, and have hands-on experience with SMS verification/A2P registration — bonus if you've worked with blockchain/wallet integrations (Polygon/Solana). Please include relevant project examples and a brief note on your SMS verification experience when applying.
