I build AI-powered web applications for clients who need the full stack - from async Python backends to polished React frontends. Recent work includes an AI job-matching platform (OpenAI, Django, React, Docker) and a funded research tool integrating PubMed, Semantic Scholar and OpenAlex with LLM-assisted review (FastAPI, MongoDB, Google Document AI). I've also led full React migrations, built MVPs from Figma to production, and integrated OAuth2/OIDC auth flows. I work best in autonomous setups where I'm accountable to outcomes, not hours. I communicate clearly, deliver working software, and flag problems early.
