Projects that make technical ideas tangible.
I’m Herman, an engineering student at Lund University. This site collects projects around observability, extended reality, and digital accessibility: an OTLP pipeline in Go, traces explored by ear, math curves turned into sound, and mixed-reality course prototypes.
01
Accessible Observability
A small trace viewer where span depth, service, duration, time, and errors each get an audible mapping.

OTLP Tap
A Go project for following OpenTelemetry data through the parts below the dashboard: receive, decode, process, store, query, and visualize.

Sonify
A Python desktop app where a typed expression becomes a curve you can scrub through by ear. The browser demo here keeps the same interaction on one fixed curve.

AR Drone
A Unity and Meta Quest 3 prototype, made with Lund University School of Aviation, for tracking a physical drone against virtual obstacles.

Inglenook VR
A technical VR prototype of the Inglenook puzzle: eight numbered carts, constrained sidings, spline-snapped tracks, and hand/controller grabbing.

Open to workEspecially observability, extended reality, digital accessibility, and systems where the hard part is making the prototype real.
