I'm a senior full-stack developer with 25+ years of experience, working remotely with US companies since 1999. I'm looking for a remote senior engineering role, full-time or contract.

My core stack is Python/Django and TypeScript/React, with a strong backend foundation and extensive AWS experience. I've architected a multi-tenant RAG platform with AI agents and third-party integrations using Python, pgvector, and OpenAI, Claude, and Gemini APIs. My work also spans healthcare EHR systems, fraud detection, gaming platforms, and learning management systems.

I've led development teams and mentored engineers while staying hands-on with architecture and implementation.
