Engineer · I own the outcome
Welcome. This is my personal website. Feel free to look around, check out my other sites, apps and tools. I'm always open to new ideas, and would love to get in touch.
01 — On the web
Static sites served from a single VPS, built with Hugo or plain HTML and deployed from git. No CMS, no database, no tracking.
02 — Apple platforms
Native software for iPhone, iPad, Mac and Apple Watch. Swift, SwiftUI, and whatever framework the job actually needs.
iOS · iPadOS
The Czech card game for four players, scored properly.
Record a live game card by card, or play against three computer opponents. Ten stages plus the maturita exam, corrections in any stage, and a result you can share as a picture. Everything stays on the device.
iOS · iPadOS
Apple Health activity, summarised from a day to a year.
Steps, distance, elevation, exercise time and workouts become week, month, quarter and year statistics — with charts you can zoom into, workout routes and splits, and no data leaving the device.
macOS · iOS · iPadOS
Paste a screenshot, mark it up, copy it back.
A Skitch-like annotation app in one codebase for Mac and iPad/iPhone. Paste one image, add arrows, text, shapes, marker or stamps, crop it, then copy or save as PNG — nothing else, by design.
iOS · iPadOS
A ZX Spectrum maze classic, loose on iOS.
A port of the ZX Spectrum maze game: 244 rooms, eight-direction movement, doors and objects to carry and swap. The simulation is a separate, unit-tested core; SpriteKit only draws it.
03 — Open source
Small, focused utilities released under permissive licences. Everything else is on GitHub.
A tiny HTTP server that accepts any payload and stores it — to the filesystem or PostgreSQL, with token auth, TLS and Docker examples.
A Z80 and ZX Spectrum emulator that renders the ULA output as Unicode blocks and braille characters, right in the terminal.
A tiny jQuery gallery: point it at a container of images and it turns them into a lightbox.
04 — About
I'm a software engineer from Czechia. I have spent the last decade building Go backends — internal platforms, onboarding, billing, support tooling and automation — and I build native apps for Apple platforms in my own time.
I take systems from idea to production and stay responsible for them: architecture, implementation, operation and the decisions in between. In the age of LLMs and agents, writing code is the easy part — knowing what to build, keeping it correct and standing behind it is the job.
