About

I came to engineering from economics, wanting to build real systems rather than model them. I taught myself in — starting with Linux at Engeto in Prague, intensive study, and stepping straight into 24/7 production operations.

The first job was support and incident response at a global content delivery network. I stayed because I loved the analytical challenge: something broke in production, and you have to work out the root cause under real pressure.

Everything since has been that instinct at a larger scale. Keep systems up. Then build them so they stay up alone. Now shape what should be built at all — and build that too.

The economics never went away. It is still how I judge whether a piece of work was worth doing: hours returned, operating costs saved, and leverage created.

Today I am Founding Product Engineer and fourth on the team at Glow, shaping the product vision for real-time multiplayer automation and building the core platform alongside the team.

I have never stopped studying. Eight years in, I am still deepening my technical craft every week across distributed systems, product design, and compiler/runtime architectures.

Based in Prague. I work in English and Czech, applying economic principles of incentives, leverage, and efficiency to software systems.

What I learn from

Not a course catalogue. The people, books and habits that shaped how I think — and what each one gave me.

Where it started
coding school · Prague

A classroom in Prague, evenings, before anyone would hire me. This is where IT caught me and did not let go.

For the work
DevOps · YouTube

Where the operations years got their vocabulary — containers, pipelines, Kubernetes explained by someone who had run them.

system design · YouTube

The diagrams behind the systems everyone uses — how they scale, where they break. The reference I go back to before I decide how something should be built.

system design · YouTube

How large systems are shaped and why they fail — the thinking behind a platform serving many companies from one place.

courses · Andrew Ng and others

Where the AI I put into workflows stops being a black box. Short courses, done properly, on the parts I actually ship.

n8n · Make · Zapier
the competition

Studied end to end. You cannot decide what to build better without having used what exists.

For the pleasure of it
mathematics · YouTube

Grant Sanderson explaining linear algebra and neural networks by drawing them. Not for work — for the feeling of finally seeing why something is true.

science · YouTube

Dominic Walliman’s maps of whole fields — physics, mathematics, computer science — on one sheet each. The habit of asking where a thing sits before learning it.

Economics
reading

The degree, and everything I have read since. Still how I judge whether a piece of work was worth doing.
