Software engineer based in Zurich. Last 10+ years I've been building infrastructure at Meta, Google, and Booking.com — recording tooling for XR devices, data validation platforms, factory calibration pipelines, testing frameworks. Mostly the kind of stuff that pages you when it breaks.
I kept looking up how things actually work — databases, distributed systems, data pipelines — and most of what's out there is either too shallow to learn from or too academic to apply. I wanted something practical: here's how it works, here's why it matters, here's where it breaks. That's what I try to write. Short reads, no filler, just enough depth to actually be useful.
