About this gig
Your app broke. I'll fix it. Your idea needs building. I'll ship it.
I'm a Base44 expert and vibe coding developer working across Base44, Lovable AI, Bolt.new, Replit - the platforms where most AI apps are built and most AI apps break.
Most AI-generated apps fail the same way: broken auth, corrupted state, logic loops, and API calls that never fire. I've seen every pattern. I know exactly where to look and what to cut.
- Base44 bug fixing, logic loops, broken auth, AI-generated code debugging
- Lovable AI app hotfix and code cleanup
- AI SaaS MVP development + Supabase backend integration
- Vibe coding prompt engineering for scalable, clean builds
- Vercel deployment, Capacitor native app conversion, App Store + Play Store upload
- Base44 migration to WordPress
This is built for non-technical founders, solo builders, and startup teams who used vibe coding to move fast and now need a real developer to take it across the finish line.
Drop me your broken app, your stalled MVP, or your deployment problem. I'll tell you exactly what needs to happen then I'll go do it.
No fluff. Just working apps.
