About this gig
Your Base44 app looks great in the prototype, then deployment reveals broken integrations, missing data, authentication errors, or workflows that stop cooperating. Replit AI and Lovable AI make building faster, but turning an AI-built prototype into a dependable product takes the right debugging, integrations, and deployment setup.
I help founders and businesses repair AI-built applications. Whether your Base44 app needs bug fixing, Supabase integration, Replit AI troubleshooting, Lovable AI fixes, API connections, or production deployment, I can identify the issue and implement a practical solution.
Services include:
- Base44 bug fixing
- Base44 integration
- App deployment
- Replit AI troubleshooting
- Lovable AI fixes
- Supabase integration
- API connections
- Database setup
- Authentication fixes
Tools: Base44, Replit AI, Lovable AI, Supabase, APIs, GitHub, Vercel, custom code, and AI tools.
Send the issue and lets get your app stable, connected, and ready for real users today.
