About this gig

Need a complete web app built end to end? I develop full-stack applications with Next.js and React on the frontend and FastAPI or Node.js on the backend clean, fast, and production-ready.


I've shipped real full-stack products, including a multi-tenant Voice AI CRM and internal dashboards with secure APIs and database integration. Whether you need a simple app or a complex system with authentication, payments, and third-party integrations, I deliver well-structured code that's easy to maintain and scale.


What you get:

  • Responsive frontend in Next.js / React
  • Reliable backend with FastAPI or Node.js
  • Database integration (PostgreSQL, MongoDB)
  • Authentication, REST APIs, and clean documentation
  • Full source code


Tell me what you want to build and I'll recommend the right setup, stack, and timeline. Fast responses, ready to start right away.
