Understanding of clean code principles, error handling, type hints, and maintainable design

API Engineering

Hands-on experience building RESTful APIs using Flask, Django, or FastAPI
Knowledge of authentication and authorization mechanisms (JWT, OAuth2)
Experience implementing API versioning, request validation, and structured error handling
Understanding of performance considerations such as throughput, latency, and caching
