> ./about --me
I'm a Generative AI & LLM Infrastructure Engineer living at the intersection of data engineering and AI. I don't just train models — I architect the systems around them: the pipelines that feed them, the vector stores that make them smart, the platforms that keep them reliable at scale.
Right now I'm building Feature Infrastructure and the ML Platform at Wells Fargo, shipping production GenAI systems on Azure and GCP. Previously I've built at Netflix, J. P. Morgan, First Republic Bank, and UNICEF — each role a layer deeper into the AI and data stack.
When I'm not wrangling distributed systems, I write on Medium about the system design patterns that actually matter in production.

I write about distributed systems, system design patterns, and AI — with the candour most engineering blogs avoid.
