I build secure Python backends and AI features for health-data products in the EU and Switzerland. Founding backend engineer at Aineo, a Swiss AI platform for clinics, doctors' offices and municipalities. It handles clinical form creation and long-form transcription. I built the backend and infrastructure from scratch. WHAT I BUILT AT AINEO • FastAPI backend, PostgreSQL + pgvector, Redis and Celery, on Swiss data-residency infrastructure • Database encryption, secrets management and tenant-isolated access control for sensitive data • RAG pipeline with hybrid retrieval (vector + keyword, reranked) and a quality check that hands low-confidence answers to a human • Integrated a multi-provider LLM gateway with failover and streaming responses (under 300ms to first token) BEFORE THAT • Omni HR: multi-tenant HR and payroll SaaS, 30k+ users across 50+ companies (Django, Kafka, RBAC) • Camaradly: built the backend from zero to launch WHAT I CAN DO FOR YOU • Get your backend ready for a clinic or hospital contract: encryption, audit logs, access control, EU data residency • Add AI features without patient data leaking to LLM providers • Build and maintain your Python backend long-term I work alongside your compliance lead. I implement the technical controls; they sign off. 8+ years in Python, Django and FastAPI. AWS Certified AI Practitioner. Building a health product that handles sensitive data? Send me the details and I'll reply with how I'd approach it.
