Products in production across web, iOS and desktop — database schema to last pixel, design to deploy. Mostly solo, always shipped.
The office World Cup, played to win.
Cubicle Cup replaces the office sweepstake spreadsheet with a private prediction league. An organiser sets it up in under a minute, colleagues join with a code, a display name and a PIN, and the leaderboard rescores itself the moment a match ends.

I’m David — a developer and designer in Reykjavík who builds products end to end rather than one slice of them.
That means the same person picks the problem, draws the interface, designs the schema, writes the Swift or the TypeScript, sets up the deploy and answers the support email. It keeps the decisions coherent and the feedback loop short.
The work on this site is real software with real users, not concepts. Each case study covers what the product actually had to solve, the approach I took, and what it does today.
Interface, interaction and the words on the screen. The design is not a layer on top of the build — it is the same job.
TypeScript and Next.js on the web, Swift on Apple platforms, Rust and Tauri on the desktop. Postgres underneath most of it.
Schema design, migrations, auth, background jobs, deploys and the boring reliability work that keeps a product alive after launch.
