Selected work

Products I designed and built on my own, from the first commit to the store listing.

Budgetory

A multi-currency personal finance app for iPhone and Android

iOS & Android app

Role: Solo developer
Status: Live on the App Store for iPhone; new iOS and Android versions in review

Income, expenses, budgets, savings goals, accounts, recurring transactions, credit cards with installments and holdings such as gold and foreign currency
Offline first: idempotent writes and client-generated IDs, so the app stays usable without a connection
Home-screen widget with a safe-to-spend forecast, fed by a shared snapshot with no network calls
Custom Swift and Kotlin modules, over-the-air JavaScript updates, six languages, full accessibility support

Stamp

A desktop app for Linux, macOS and Windows that formats SD cards as FAT32 at any size and loads a zip onto them

Desktop app

Role: Solo developer
Status: Open source under the MIT license; releases for Linux, macOS and Windows

Formats as FAT32 at any size, which the stock formatters refuse above 32 GB, then copies a zip onto the card
Three native apps: GTK4 and libadwaita on Linux, SwiftUI on macOS, WPF on Windows, sharing one UI-free core per platform
Safety first: the system disk can never be selected, every step is logged and the zip is checked before anything is erased
On Windows the FAT32 structures are written by hand; 158 tests across the three apps, packages built in CI

Scrap Baron

A pixel-art scrapyard tycoon game for phones and the browser

Game

Role: Solo developer
Status: Playable in the browser now; iOS and Android versions being prepared for release

A day in four phases: set prices, weigh and haggle at the scale, sell to wholesalers, read the report; catch fraud with a magnet or by tipping the sack
Three tiers from a neighbourhood yard to a recycling plant, 25 achievements, 18 cosmetics and an endless mode
No game engine: Canvas 2D at integer scale, all art painted in code, synthesized Web Audio, about 160 KB gzipped
Deterministic, seeded simulation with exact save restore; about 330 unit tests and 28 end-to-end tests

Pizza Assassin

A comedic pixel-art stealth platformer for iPhone and Android

Game

Role: Solo developer
Status: Being prepared for release on the App Store and Google Play

40 levels across 6 worlds: guards patrol, investigate and chase; lure them with a slice, hide under a pizza box or turn off the lights
Three stars per delivery, 120 hidden toppings, ghost runs, outfits, 18 achievements and leaderboards on Game Center and Play Games
Levels are ASCII maps and the pixel art and chiptunes are generated by scripts; game logic runs without the scene tree
371 unit tests, 18 scripted playthroughs and store automation for six languages
