Weird things I build
when nobody asked.

Frontend developer by day. This is the playground: apps, sites, AI videos, MCP servers and whatever else seemed like a good idea at 1 a.m. Yes, including this intro.

Straight from the Lab.

A website, a video channel and an app. The other twelve, games and ghosts included, live in the Lab.

Juleruten

Snack Tier

Ranking every snack on earth.

A YouTube channel where a chef mascot ranks food — chips, sodas, pizza styles, Halloween candy — in tier lists. Written, generated, cut and published with an automated pipeline I built; several videos a day, cross-posted to TikTok.

Surd

Keep your sourdough alive.

Feeding reminders, stages and rise for every starter, a baking plan that tells you when the dough peaks, and a dough calculator. Built in SwiftUI around the "Living Craft" design system — marigold, charcoal and bubbles.

02 — About

Inventor at heart.
Nerd by nature.

Ever since I was a kid I wanted to be an inventor. These days that means webapps, native apps and automations — and the occasional cookbook.

By day I'm a frontend developer. By night I build whatever's bugging me: a to-do app that stays out of the way, a sourdough tracker, a horror game set in a slaughterhouse, an app for planning who to haunt, an MCP server so Claude can check domain names for me.

Custom over off-the-shelf, every time — even when off-the-shelf would have taken ten minutes. Fun facts: I'm colorblind, I used to be a viking re-enactor, and I've been house photographer at Tapperiet for twenty years.

Say hi.
Or file a bug.

Ideas, questions, a broken link, or what beer goes in which dish. If it needs a deadline and an invoice, that is a job for Codebit.
