Python backend developer with 10+ years of commercial experience, most of it Django. Started in PHP, shipped full-stack Python with Vue and React, then moved fully to backend. Recently I design FastAPI and Django REST microservices for FinTech and multi-tenant B2B SaaS: PostgreSQL (including row-level security), async SQLAlchemy 2, workers, WebSockets, and third-party integrations. Comfortable with Docker, Kubernetes, AWS, and Azure. I use specification-driven delivery so backend work stays reviewable before it lands.
