I will develop and secure backend apis in python or nodejs

Are you looking for a backend developer who writes secure, clean, and production-ready code?

Many applications suffer from broken authentication, SQL injection, IDOR, or exposed endpoints that require costly fixes later. I build and secure backend architectures designed to resist common OWASP threats right from the start.

What I can help you with:

- RESTful API development using Python (FastAPI/Flask) or Node.js (Express)

- Secure authentication & authorization (JWT, OAuth2, session tokens, RBAC)

- Vulnerability fixing and input sanitization (SQLi, XSS, rate-limiting, CORS)

- Database schema setup and secure querying (PostgreSQL, MongoDB)

- Bug fixes, refactoring, and code hardening

Why choose my service:

- Clean, maintainable, and well-documented code

- Strong focus on application security best practices

- Fast turnaround and transparent communication

Please message me with your project details before placing an order so we can confirm the technical requirements and timeline.
