Esperienza lavorativa

LinkedIn

Senior Backend Developer (FastAPI / PostgreSQL)

LinkedIn • Freelance

Jun 2026 - Present • 4 mos

Contract role on the internal SaaS platform of a French wealth-management advisory firm. I own the security, access-control and database track of their FastAPI + PostgreSQL platform. - 96 merged pull requests in four months; I review the team's auth, RBAC and secrets changes - Audited role-based access control, found live data-exposure paths, fixed them and added a CI linter that blocks the unsafe pattern - Implemented tenant isolation with PostgreSQL row-level security and a least-privilege application role, backed by parity tests - Kept secrets out of error reporting (recursive Sentry scrubber, Pydantic SecretStr) and closed a login timing side channel with a bcrypt decoy - Atomic migrations, correct 409/404 responses instead of 500s; every fix ships with tests that fail on the old code
