I help secure your web applications with professional user authentication and robust security systems. Using technologies like *PHP*, *Node.js*, and *JWT*, I implement:
- Secure user login/logout
- hashing & validation
- Role-based control
- Two-factor authentication (2FA)
- Token-based authentication (e.g. JWT)
- Session management
- Form/data validation
- Basic API protection
Whether you're building from scratch or upgrading an existing system, I’ll ensure your platform protects user data, and follows modern web security practices.
