Work with me
Software, built with the same care as my own apps.
I am an independent software developer in Unterhaching, near Munich — a Mac, iOS and iPad developer, available for projects. Most of my work is native macOS and iOS: considered, privacy-minded, and shipped end to end. If you have seen the apps on this site, that is the level of finish I bring to client work.
What I do
Where I can help
Native macOS & iOS apps
SwiftUI and AppKit, built to feel at home on the platform — not a cross-platform shell. From a single-purpose menu-bar tool to a full document app.
On-device and privacy-first
I default to running things locally — on-device models, no cloud round-trips, no tracking. If data does not have to leave the machine, it does not.
From idea to the App Store
Concept, design, build, localisation, notarisation and release — including the unglamorous parts: entitlements, sandboxing, review, updates.
3D and graphics
Metal rendering, Gaussian splatting and real-time 3D — the area I keep coming back to (RadianceKit, RadianceView, Unreal Engine demos).
A second pair of hands
Code review, a tricky Swift 6 concurrency problem, a performance bottleneck, or picking up an existing project — not every engagement has to be a whole app.
How it works
Small, direct, one person
It is a one-person studio, so you talk to the person actually building the thing — no account managers, no hand-offs. We scope the work together, I keep you in the loop as it takes shape, and you get something that works rather than a demo that almost does. Fixed scope or an ongoing arrangement both work.
I work as a freelancer under German tax law (§18 EStG, software development); invoices show VAT. Remote by default, in and around Munich in person when it helps.
