“calm, drama-free MLOps”
— the whole thesis, really
§ 01 — hello

Nice to meet you.

I wrangle messy, real-world data into products your users actually love — from classical ML to agentic systems — delivered with calm, drama-free MLOps. This is where I write it down so I don’t forget how.
§ 02 — what I do

What I do

Ten-ish years of shipping ML at scale — classical pipelines, deep learning, on-device inference, and more recently, agentic systems. Tech lead by day, still a student of the craft at night.

§ 03 — currently

Currently

Right now: tiny sorcery to run big brains on small chips — quantization, distillation, and the gnarly art of squeezing transformer-class models into edge silicon. Plus a side quest in local LLMs with manners: retrieval, tool use, and eval harnesses that don’t lie to you.

Say hi
