AI Engineer · From LLM applications to production operations.
I build AI services and the systems that keep them running: Service (RAG, agent workflows), Platform (LLM gateways, guardrails, serving + inference optimization, and observability).
- Previously at Toss Bank (15M+ user) — built and operated customer-facing and internal LLM services, then the shared LLM platform and LLMops behind them.
- early MLX contributor — optimizers, Transformer components, and cosine-similarity loss.
- Research — first author KDD 2023 (oral) and WWW 2025 (poster).
Interested in building AI-first products with small, ambitious teams. Canada first; also exploring the UK and Europe.
