I build analytical dashboards, REST APIs, and web applications at Fractal Analytics, mostly with Python and React. I care about software that’s clear, dependable, and built to handle real work.

A little about me
Most of my work is on analytical dashboards for enterprise clients: the screens people use to answer real questions, and the APIs and data work underneath them. Since 2018 I’ve also built REST APIs, e-commerce features, web scrapers, and a battery simulator web app.
I studied computer science, went on to a master’s in data science, and still tinker with a Raspberry Pi for fun. Away from the keyboard I’m usually on a mountain trail or reading philosophy.
This site is where I keep practical notes on what I learn and build. They’re written for my future self; if one saves you an hour of debugging, even better.
