I will debug auth, API, database and deployment issues in your app
Artur T.
About this gig
I troubleshoot and repair existing web applications that are not behaving as expected.
Problems I work with include:
- React or TypeScript bugs
- Supabase authentication, database, or RLS problems
- API and third-party integration failures
- broken login or session flows
- frontend-to-backend errors
- deployment and environment issues
- regressions and unstable user flows
I diagnose the failure at its source, make changes only when necessary, and test the result. I can work with existing applications, including projects created or accelerated with tools such as Lovable, Bolt, Cursor, Replit, or similar AI-assisted development tools.
Before ordering, please send the issue description, screenshots or error messages, relevant tech stack, and access details if available.
Thank you !
