Jahid Hasan
À propos de ce service
Are you having trouble with Supabase authentication, RLS policies, database errors, or your Next.js app? Maybe you've started a project but need someone to fix issues or finish a feature.
I'm a full-stack developer with hands-on experience building and maintaining SaaS platforms and business applications using Next.js, React, Node.js, PostgreSQL, and Supabase.
I can help with:
- Supabase login, signup, and session issues
- RLS policies and permission errors
- PostgreSQL queries, database errors, and CRUD operations
- Next.js bugs, API routes, and server-side errors
- Frontend and backend integration
- Broken features and unfinished functionality
- Issues in AI-generated or traditionally built apps
I don't just try random fixes. I look into the cause, make the necessary changes, and test the affected functionality.
If you're stuck, send me a message explaining the issue and what you've tried so far. I'll review the details and let you know how I can help before you place an order.
