I build apps and the agent tooling that builds them.
Principal Android Engineer at Airalo · Google Developer Expert for Android · Berlin
I build mobile apps, desktop apps, CLIs, and whatever else a problem needs. Lately most of my time goes into the agent side: skills, subagents and workflows that take a change from discussion to a merged pull request.
- FeedFlow — minimal RSS reader with cross-device sync and a reader mode. Android, iOS, macOS, Windows, Linux.
- ReaderFlow — privacy-focused read-it-later app that works offline.
- Difftray Mobile — companion to Difftray: pair with your Mac and review changes from your phone or tablet, with no cloud backend.
- PomoStats — unofficial App Store Connect client for Android.
- CueUp — video presentations: the video on the projector, the controls on your screen.
- Slashgrab and Shellporter — small macOS menu bar utilities.
- mgkit — my workflow for building with agents: roast, plan, execute, review, ship.
- Difftray — local-first macOS app for reviewing Git changes across projects. Tracks what you reviewed, flags drift, and turns your review notes into prompts for your agent.
- regesto — a plain-markdown knowledge base that agents read before they act.
- claudup — keeps one Claude Code Remote Control bridge running per project on an always-on Mac, so every project is its own environment in the Claude app.
- pcenter — publish and manage Microsoft Store releases from the command line.
- RSS-Parser — Kotlin Multiplatform parser for RSS, Atom and RDF feeds.
- klead — Kotlin Multiplatform library that extracts clean article content from web pages.
- Bases Kanban Toolbox — improves Obsidian's native Bases Kanban boards: manual card order, compact cards, collapsible columns and a card popup.
- HTML Shelf — browse and read the HTML files in your vault, on mobile and desktop, without leaving Obsidian.
