Built an app with Lovable, Bolt, Cursor or another AI tool and now it's stuck? I'll fix it.

I'm a UK software engineer who builds production apps with React, Next.js, Supabase and Postgres, and I fix the things AI builders get stuck on: errors and blank screens, logins that won't work, Supabase errors and row level security, data showing for the wrong user, payments and API connections, and getting it deployed.

Invite me to your repo or project (never send passwords), tell me what's broken, and I'll fix it, test it and explain what was wrong in plain words. If it's bigger than expected, I'll tell you before doing anything extra.
