You get a REST API built the way production teams expect it: documented, tested, secured, containerized, and observable — not a script that dies on Monday. I'm a software engineer trained at 42 School (rigorous peer code review, C-level fundamentals) and author of DataGuard API, an open-source production-grade FastAPI service: JWT auth with refresh rotation, Argon2 hashing, encrypted sensitive fields, audit trail, pytest suite, and a CI pipeline with Bandit, pip-audit and Gitleaks.
