I build fast, accessible websites and web apps for businesses and non-profits, with deep expertise in performance.
Software Engineer, Web Developer, Performance and Observability, Vibe Coder
Six live projects, from multiplayer games to machine-learning forecasts. Every one is a click away, and every one was measured with Lighthouse on 20 October 2026.
Multiplayer web app
Browser party games for friends and teams: caption memes, draw and pass, Word Spy, trivia and more. No ads, no accounts, nothing to install.
Real-time group app
Everyone swipes through movies or TV shows on their own phone. The moment the whole group likes the same title, it's a match.
Data and machine learning
Live occupancy and a 7-day forecast for a Swiss thermal spa. A gradient-boosting model learns from visits, weather and holidays. An independent project, not affiliated with the spa.
Live data dashboard
Live water temperatures for the Alte Donau, Neue Donau and the Danube in Vienna, with flow and water level set against 24 years of history.
Client website
Portfolio site for a goldsmith and gem setter in Bad Goisern, Austria. Full-bleed video, a curated 2026 collection and a German and English version.
Non-profit website
Home of a cross-denominational initiative for worship music from Austria, with a song directory, artist pages, events and a newsletter.
I'm a software engineer specialising in performance and observability. I take projects from idea to launch, and AI pairing lets me ship fast without cutting corners.
Fast, accessible websites for companies, craftspeople and non-profits, built to rank on Google. Like the gem setter's portfolio and Österreich lobt above.
Interactive apps with real-time features that run in any browser, no app store needed. Like Party Game Hub and Movie Swiper.
Live dashboards and forecasts built on sensors, public data or your own data. Like the Soleuno occupancy forecast and the Vienna water temperatures.
Already have a website? I measure its Core Web Vitals, find what slows it down and fix it. Five of the six projects here score 97 or higher for mobile performance in Lighthouse.
Core Web Vitals for your visit, read in your browser with the PerformanceObserver API. Nothing is sent anywhere.
