Software that does one thing, properly.
I'm a developer from south-east Styria and a student at HTL Kaindorf. I build macOS and iOS apps, developer tools and automations — and I help people nearby with websites, repairs and everyday technology.

ÖffiGo
Austria's public transport — truly native.
Real-time departures, journey planning and live disruptions for all of Austria, in a modern, fast interface. ÖffiGo pulls its Austria-wide transport data from VAO / HAFAS, overlays Wiener Linien open realtime for the Vienna subway, and always labels whether a time is live or straight from the timetable.
live positions · beta
An honest label beats a confident guess.
Official operator realtime is what ÖffiGo shows first, clearly separated from the timetable. Live vehicle positions run as a beta on a deliberately sparing on-demand lookup, and ÖffiGo only adds a prediction of its own when the measurement basis behind it is fresh and approved. The whole data status is public.
-
Live departure board
Your nearest stop, departures for every mode, and realtime where it's available — including delays, platform changes and disruptions. For the Vienna subway it even overlays Wiener Linien realtime where VAO ships only a schedule.
-
Journey planner
Plan your route with all transfers, the walk to the first stop, and a depart-at or arrive-by time.
-
Live map & nearby stops
Stops around you on the map, plus live vehicle positions where they are available — a beta capability that fetches sparingly instead of polling the network.
-
Indoor station guidance
At mapped major stations, transfers can use OpenStreetMap indoor data for stairs, escalators and lifts.

What I can help with
Alongside my own projects I help people and small businesses in the area with everyday technology. On-site nearby, remote everywhere else.
Website development & hosting
Modern, fast portfolio, business, and club websites — built with hosting, domain setup, and ongoing maintenance in mind, so everything runs from one place.
Electronics repair & setup
PC and Mac repair, setting up new devices, printers and peripherals, getting things running again.
Technical support / IT help
Fixing everyday tech problems, backups, updates, and clear advice without the jargon.
Custom tools & automation
Small macOS utilities, scripts, and automations for when off-the-shelf software isn't enough.
about
The short version.
I live in south-east Styria and study at HTL Kaindorf. Most of what I build starts as a problem I ran into myself: a workflow that takes too many steps, a device that won't cooperate, an app that should exist and doesn't. I work with TypeScript, Swift and Python, but the stack matters less than whether the finished thing actually gets used.
