Hey, I build things - systems, tools, products, and the occasional experiment that sends me down a rabbit hole. Over the years, I've worked across the stack - frontend, backend, infrastructure, deployment. I also created Granova, a platform for grocery stores.

What really draws me in are probability, statistics, machine learning, and the way financial markets behave like a huge math problem - a high-dimensional, non-stationary system where the structure keeps changing as you study it. It's far too complex to "solve" but endlessly fun to explore.

This site is where I post projects, notes, and whatever else I'm thinking about.
