Secure Backend API Development

Project: Security-first REST API with comprehensive input validation

Overview: Designed and implemented a backend API with security integrated at every layer—from request validation to authorization enforcement to secure data handling.

Security Controls Implemented:

• Schema-based request validation with strict type checking
• Role-based access control (RBAC) enforced at every endpoint
• Parameterized queries to prevent SQL injection
• Rate limiting and request throttling
• Comprehensive audit logging (excluding sensitive data)
• Secrets managed via environment-specific vaults

Technologies: Python (Flask/FastAPI), PostgreSQL, Redis (caching/rate limiting), Docker

Result: Zero security findings in external security audit; system handling production traffic with no security incidents.
