A collection of side projects, apps, and things I’ve built outside of work.

TriangleCore.rocks

A small shop I run with my life partner, dedicated to electronic music hardware — Eurorack modules, standalone synthesizers, and merch from independent hardware makers. We help musicians explore unique synths and give indie builders a platform to reach a wider audience.

Flora Synths (Instagram)

Our own line of Eurorack modules and accessories, sold through TriangleCore. Includes modules like the Quatrovertalius (four channels of chained attenuversion) and custom blank panels in multiple colors.

Chord to Music (iOS)

A chord progression generator for musicians. Creates authentic progressions across 13+ genres and visualizes them as piano roll, guitar tab, or chord notes — a quick way to spark musical ideas.

54321 Breath – Grounding App (iOS)

A mindfulness app that guides you through the 5-4-3-2-1 grounding technique to help manage anxiety and stress by reconnecting with your senses.

DiskViz

An open-source tool for visualizing disk usage — helps you see where your storage is actually going. Written for my own curiosity and shared on GitHub.

Wording Taboo Game

A simple German-language Tabu/Guess-It game I built for family game nights. Shows German words (with articles and translations) at different difficulty levels for vocabulary practice.
