Bratislava, Slovakia · open to work and client projects
I write the software, and I run the machines it lives on.
Developer and founder in Bratislava. I built a fleet-management platform for the car rental company I operate — then kept going and built the storefronts, the CMS engine behind them, and the servers all of it runs on.
One system, all the way down
What Fleetron is actually made of
Most stacks are described from the top. This one is worth reading to the bottom, because the bottom is where the decisions get expensive — and the bars show where they get expensive fastest.
What a dispatcher looks at: live positions, trip history, and the paperwork a trip becomes.
DNS and proxy. TLS and caching at the edge so the origin handles only what it must.
One container owns 80 and 443. Nothing else on the host binds a public port.
Three services from one repository, released together as versioned images rather than a git pull.
Sessions and background jobs. Not on the critical path — the platform survives losing it.
Trips are geometry, not two float columns. “Which trips crossed this zone” becomes one query.
Six containers on one host. The database publishes no port — the app reaches it over the compose network.
One machine, patched and watched by me. Ninety-five days of uptime at the last check.
Selected work
Seven builds, and what each had to solve
Two are live and carrying real traffic. Four are finished and waiting on a launch date. One is a tool that runs every hour so I don’t have to read classifieds all day.
