AI Engineer shipping end-to-end LLM product features—reliable, testable, privacy-first.
What I'm looking for
I’m an AI Engineer who ships LLM-powered product features end-to-end, from prototype to production. I design and build AI-enabled learning experiences—integrating LLM APIs, prompt-management, and structured-output workflows, plus retrieval over learning content and adaptive recommendations.
I balance fast experimentation with disciplined engineering: I build evals and test harnesses to measure output quality, consistency, and failure modes, then add guardrails, monitoring, and human-review steps before content goes live. My strength is full-stack delivery (TypeScript/Node.js, SQL, Supabase/PostgreSQL, REST APIs, Docker, cloud), paired with strong testing, privacy/security, and clear communication with non-technical stakeholders and education partners.
