I design, build and ship web products end-to-end — from the database schema to the last micro-interaction.
I'm a full-stack developer working at the intersection of product, design and infrastructure. I like small teams, strong opinions held loosely, and shipping software that feels obvious in retrospect.
Good software is calm. It does fewer things, more clearly, with less ceremony. I optimise for the second-time user — the one who already knows what they came for.
Single-page marketing site for Poletime, an ultimate frisbee club in Prague–Horní Počernice. Bundled with a content-managed admin UI so the team can edit hero, training info, coaches, news and mixer events without touching code.
Web app for sports teams — events with RSVPs, attendance tracking, workout logging and a leaderboard. Sign-in goes through Discord, so the tool slots alongside a club’s existing server instead of asking everyone to register again.
Christian songbook with chords, lyrics and live auto-scroll — one codebase shipping to web, iOS and Android. Full-text search across 700+ songs, ChordPro viewer, transpose/capo, Cs↔En notation toggle, stave notation, dark mode, favorites, recents and setlists. Companion Python pipeline converts source PDFs to ChordPro + staff PNGs.
Czech training diary for serious lifters — log sets with reps, weight and RPE; track progress with interactive charts (max weight, total volume, Epley 1RM); save Push/Pull/Legs as templates; export individual workouts or monthly overviews to PDF. Built as a semester project at university.
Personal website for Mikuláš Minář — Czech commentator, coach and speaker. Editorial gold-on-dark landing with sections for his newsletter, podcast and lectures, plus deeper subpages for coaching and his story.
Single-file cost calculator for Poletime training camps. Plug in head count, arrival/departure, number of sessions and the live price list — get the per-person/day cost and a line-item breakdown of accommodation, field rental and food.
Maintained fork of a popular OpenAPI → TypeScript client generator. Patches around new spec features, ergonomic improvements for monorepos, and a stricter type pipeline.
Two-day prototype for Česká spořitelna's annual hackathon — a fintech tool exploring conversational onboarding for small-business banking. Shipped end-to-end with a live demo.
Kotlin REST API for managing Mailu mail servers programmatically — accounts, aliases, domains. Drop-in replacement for the missing official API, used to script multi-tenant setups.
Tell me about it. Best fit: small teams, scoped projects, MVPs and rebuilds.
