Selected work

Tessera

Android app · open source (GPLv3) · 2026

Runs Linux desktop apps on Android as real Android apps: Debian and 2,800+ Flathub apps, each with its own window, Recents card and home-screen icon.

Runs Flathub apps without bubblewrap or user namespaces, which Android kernels lack, by building each app's file system itself.
GPU acceleration (OpenGL 4.6, Vulkan) on Snapdragon phones through a custom Mesa Turnip and Zink build.
Themes GTK, libadwaita, Qt and LibreOffice with the phone's Material You colors, live.
A touch-friendly Linux desktop mode, live per-app scaling, and per-app permissions enforced with PRoot or kernel namespaces.

SPU Archive

Document archive for a public university (SPU) · 2026

Digitizes and searches a university's personnel records, built for about 200,000 scanned files, on ordinary hardware and fully offline.

Web app and API in ASP.NET Core with PostgreSQL and live updates over SignalR.
A scanner bridge that sends documents from TWAIN scanners or watched folders straight into the archive, and a desktop backup service.
An offline, CPU-only pipeline that reads Central Kurdish and Arabic-Indic administrative forms: deskewing, table detection, digit classification and name matching, with checks that refuse a row rather than guess.
An explainer view that overlays what the pipeline saw on each page, so every result can be checked.

RP Companion

Business software for a phone-repair shop · 2026

Inventory, sales, repair tickets, customer debts, expenses, accounting and thermal-printed receipts, on the shop's Windows PC and the staff's Android and iOS phones.

Offline-first: every device keeps a full SQLite database and works without a network.
Peer-to-peer sync with no central database, through a self-hosted SignalR relay that stores nothing.
One .NET MAUI codebase for four platforms, plus a public website with an admin panel.
Unit tests, an Inno Setup installer and CI-built iOS releases; went through a full security audit with every finding tracked to closure.

phosh-termux

Linux mobile shell on Android · open source · 2026

Runs the Phosh mobile shell, Plasma Mobile and XFCE in a Debian container on Android, with the fixes that make it usable: a lock screen that unlocks under PRoot, sessions that survive Android's phantom-process killer, and relaunching without a reboot. Comes with a write-up of each diagnosis.
