software developer / styria, austria
Software that does one thing, properly.
I'm a developer from south-east Styria and a student at HTL Kaindorf. I build apps for the Mac and the iPhone, developer tools and automations, and I help people nearby with websites, repairs and everyday technology.

flagship
ÖffiGo
Transit, without the guesswork.
A public-transport app for all of Austria: departures, routes and step-by-step guidance, on the iPhone, the Apple Watch and the lock screen. Every time says where it came from, and when a transfer gets tight, ÖffiGo already has a plan B. No ads, no account.
where the time comes from
Every time shows where it came from.
Some times are reported, some are calculated, some are only scheduled. The row on the board tells you which one you are reading, and ÖffiGo's own estimate never replaces the operator's.
Departures
Your stop with every line, delays, platform changes and cancellations, and a label on each time saying whether it is live, realtime or timetable.
Plan B when it gets tight
When a delay costs you the transfer, ÖffiGo works out an alternative from where you are. It only suggests one that saves at least three minutes.
Subscriptions
Save a trip or a whole line. ÖffiGo keeps checking while the app is closed and tells you once when something changes.
Apple Watch and Live Activity
A full app on the wrist, and the next stop on the lock screen and in the Dynamic Island without unlocking.

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.

Frequently asked questions
Do you work remotely?
Websites, tools and support: yes, anywhere. Repairs and device setup happen on site in south-east Styria.
How much does a website cost?
It depends on what it has to do, and whether hosting, domain and maintenance come with it. Write me two sentences about what you have in mind and we'll talk it through.
