What I'm looking for

Remote senior or staff-level AI engineering role where I can design and own production GenAI systems end to end: RAG, agentic workflows, and LLM platforms. I value teams that take evaluation, observability, and security seriously. Especially interested in enterprise or regulated settings like healthcare. Based in Texas (US Central) and comfortable working across time zones.

At Elevance Health, I built CareAssist with Python, FastAPI, Clinical NLP, and RAG to turn clinical conversations into structured documentation and retrieve relevant patient context. It cut documentation effort by 35% while preserving source traceability and controlled access.

I also developed NexusAI, a knowledge retrieval platform that reduced time spent locating information by 40%, and built governed agent integrations and production evaluation workflows. At Apple, I developed data and conversational analytics platforms, including DataSphere, which reduced recurring data-pipeline incidents by 30%.
