I will build or fix a secure backend API for your web app
Faisal Jawed
About this gig
Is your backend slow, breaking, insecure, or just not built yet?
I build and fix Node.js backend systems for web apps and SaaS products designed to actually hold up with real users, not just work in testing.
What I can help with:
- Building a backend from scratch (REST APIs)
- Fixing broken or unreliable API endpoints
- Authentication and authorization issues (JWT, OAuth)
- Database integration and structure (MongoDB, PostgreSQL, MySQL)
- Connecting third-party services (payments, external APIs)
- Improving security and performance of existing backend
- Clean, documented code that's easy to maintain
With 5+ years of experience across different companies, I know the difference between code that "just works" and code that's actually production-ready. I focus on the second one.
Whether you need a backend built from zero or an existing one fixed, send me the details and I'll tell you exactly what needs to be done.
