I build and run research software. On the side: small tools, games and infrastructure.

Four projects told properly, then everything else. Each is marked with how much of it AI made, and the filter up top hides what you'd rather not see. Press ⌘K to jump anywhere.

Compute job platform

Slurm jobs from a browser. Researchers sign in with their AU account, pick data from ERDA and submit; a React/Node app sits in front of a cluster that grows and shrinks itself on Oracle Cloud.

why: Heavy jobs without learning Slurm, SSH and batch scripts first. Use is bursty, so a fixed cluster is either idle or full.
interesting: A queued job has to say why it's waiting while a node boots, instead of just looking stuck.

Every service on my servers, deployed and updated from one repo with Ansible and docker-compose. One command brings a machine to the state git describes.

HyperCache

Reputation systems for peer-to-peer archival: who can you trust to keep your data? Peers rate each other on whether data is really kept, built and simulated in Node.js.

Mixed-Reality Rowing Game

Row a virtual boat with two real oars. Sensors on each oar are read by an Arduino, and every stroke goes over serial into a Unity scene.

why: Rowing machines are boring, and VR controllers don't feel like oars.
interesting: Turning noisy sensor readings into a stroke that feels right, with almost no lag.

2025 – now
Aarhus University · IT-medarbejder, IT Research Tech
Building and running software for researchers:
- a scalable, easy-to-use compute job system on Slurm, with a custom React/Node web app, scaling on Oracle Cloud, OAuth/Entra ID login and AU's ERDA storage
- document and information services, integrating Overleaf and OpenProject
- trying newer software while keeping it secure, containerised, updated and monitored: OpenBao/Vault, Grafana, Docker, Ansible

Mockup note, not part of the page · suggested left gate

If this direction wins, the gate's left half goes warm graphite with the same faint orange bloom, Geist set big and tight. The three featured rows sit on a small raised panel with the AI marks; the pointer light from this page runs along its border.

The two halves then differ by hue and texture rather than light vs dark: lit graphite and crisp sans on the left, grainy plum and Fraunces on the right. On hover, a tilted drawn preview of the compute platform slides in where the grid paper used to be.

"Enter work" then needs no transition: the gate is already this page's colours.
