What I'm looking for

I seek senior roles building production LLM and AI platforms, hands‑on with full‑stack delivery, strong TDD culture, and cross‑functional impact.

I am a Senior AI and Full‑Stack Engineer with deep experience building production ML systems, scalable APIs, and user‑facing applications. I design and ship end‑to‑end solutions from LLM fine‑tuning and RAG pipelines to high‑performance REST/GraphQL backends and responsive frontend experiences.

At recent roles I led AI platform initiatives—owning technical vision, reducing latency, implementing policy‑as‑code compliance, and delivering measurable product improvements such as large reductions in manual validation, post‑meeting admin time, and API response latency. I champion TDD, mentor engineers, and establish operational practices to improve reliability and developer productivity.

I seek to apply my expertise in LLMs, distributed RL, vector search, and cloud architecture to build impactful products that balance performance, compliance, and excellent user experience.
