About

I’m a software engineer in Sweden. This page is the slightly-less-terse version of the home page — what I work on, what I build, what I’m currently nerding out about.

Software

Software is both work and hobby. I work across the stack — web frontends, backend services, embedded firmware on small microcontrollers, command-line tools, whatever the project needs. Rust is the language I reach for when I get to choose.

Coding agents have changed how I think about personal software. Instead of bending an off-the-shelf app into something close to what I want, I increasingly just write my own — exactly how I like it. The clearest example: after years on Obsidian I now use a small LLM-enhanced note-taking app I built for myself.

A couple of side projects that live here:

• Aphid — the Rust static site generator that builds this site
• bea-rs — a file-based task tracker for developers and AI agents

Electronics and 3D-printing

I have a makerspace at home — a well-equipped electronics lab, a handful of 3D printers, and a decent-sized workshop. Most of the boards I design end up as small utilities for one of the other projects on this list — a sensor here, a controller there — and the printers fill in whatever I can’t buy off-the-shelf.

Electric vehicles

Aphid EV is a Beetle-to-Leaf-drivetrain conversion with its own build journal. Previously I’ve build electric bikes that are a bit to powerful to call a bike. Electric convertions of mopeds using huge BLDC motors and more.

Bikes

I ride MTB, and the bikes in the household are a steady stream of small projects. I keep mine and the kids’ bikes running myself — fresh paint jobs, drivetrain upgrades, suspension service, the occasional component swap just because.

AI and homelab

A small homelab handles the usual self-hosting, plus a growing pile of IoT and home-automation bits. Lately a fair bit of my tinkering has been around AI tooling — agentic coding, MCP servers (see bea-rs), and figuring out what’s actually useful versus what’s hype.

This site

A notebook, mostly. The wiki holds project pages and notes I want to find again; the blog is for the occasional longer write-up. It’s happened more than once that I’ve googled some problem and landed on a blog or forum post from years ago — written by me — describing the same issue and, with any luck, the fix. This site is partly an attempt to make that happen on purpose. Built with Aphid, hosted on GitHub Pages.
