I will build or fix your SaaS MVP web app complete with user authentication, a working dashboard, payment integration, and a production-ready database — so you can stop debugging and start shipping.

SaaS dashboard UI with role-based access control
Supabase or PostgreSQL database design and setup
REST API and third-party API integration
Bug fixing and code review on existing Next.js or React apps
Performance issues, broken deployments, and Vercel fixes
