About me
I'm Shane Kristoff, a vibe coding expert who rescues and secures apps built with Lovable, Base44, Bolt.new, and Replit. When an AI builder leaves bugs unfixed, security holes open, or features half-built, I find the root cause and fix it properly, not just patch the symptom.
My focus is Supabase security: row level security, exposed API keys, and auth policies that AI builders routinely skip. I also handle migrations off builder lock-in, native app conversion, and getting your project deployed with a real custom domain.
Send me your app link and what's breaking. I'll tell you what's wrong.

I help founders and small businesses fix, secure, and finish apps built with AI tools like Lovable, Base44, Bolt.new, and Replit. When these builders leave bugs unresolved, security gaps open (especially unprotected Supabase databases with row level security turned off), or features half-built, I dig into the actual code and fix the root cause rather than patching symptoms. My work covers: Debugging and fixing broken functionality in Lovable, Base44, Bolt.new, and Replit projects Supabase security audits: row level security, auth policies, and exposed API key cleanup Fixing broken payment integrations, signup, and login flows Migrating projects off builder platform lock-in onto independent hosting Converting web apps into native iOS and Android apps Custom domain and DNS setup, and production deployment I built and documented a set of demo projects covering each of these areas — from a deliberately broken Lovable app fixed end-to-end, to a Supabase project moved from an exposed, unprotected state to a fully locked-down one — to show exactly how I approach a real rescue job before a client hands over access to their own app.
Lovable bug-fix rescue
Jan 2026 - Feb 2026 • 1 mo
Build a small Lovable app on purpose with 2-3 realistic bugs — a broken signup flow, a form that doesn't save to Supabase, a UI element that doesn't render on mobile. Fix them yourself, then screen-record a short before/after: "here's what was broken, here's the fix, here's why it happened." This directly demos your #1 gig category.
