Lovable, Bolt, Replit or Cursor got your app 80% there and now it's stuck? I take AI-built apps the last mile: auth, Supabase security, Stripe, deploy, and the bugs the AI can't see. 11 years shipping production .NET/React, plus a summer spent moving six of my own Lovable apps onto GitHub and Supabase, so I know exactly what these tools leave broken.
