I build data-driven products, from model to shipped app.
Software engineer · MSc Data Science · glider pilot
I fly gliders — no engine, just reading the air and managing energy. Which, it turns out, is exactly how I like to build software.

02 / TRAJECTORY
The route so far
A logbook of waypoints — apprentice to co-founder, with a study or two and a glider along the way.
IT Apprenticeship
Swisscom (Schweiz) AG
Four years to Computer Scientist EFZ — backend, web apps and iOS. Picked up a Swisscom Young Champion award along the way.
Zimmermann Informatik
Self-employed · Vitznau
Ran my own little shop: web apps for Swisscom, sites for local clubs, and photography on the side. First taste of owning the whole thing.
Application Developer & Board Member
analogDigital AG · Bern
Full-stack development, project management and client consulting — plus a seat on the executive board.
BSc Business Information Technology
BFH · Business Data Analytics
Best Bachelor Thesis in my cohort — a knowledge-graph study of Confluence data, with SBB as industry partner.
Co-Founder & Fullstack Engineer
indigo online AG · Bern
Grew a Holacracy-run agency from the ground up. Shipped full-stack apps for SBB, Swisscom and others; co-lead org development and mentor apprentices as a certified vocational trainer.
Swiss Army
Motor Vehicle Specialist · Cat CE
A year on a rather different class of heavy machinery. Good for the perspective.
MSc Applied Information & Data Science
HSLU · ongoing
Bridging engineering with analytical depth — turning a decade of building into a sharper data-science practice.
Glider pilot
Working toward PPL & future FI ratings
The part that rarely makes it onto a CV. Active glider pilot, chasing lift and, eventually, a power licence and instructor ratings. Engines optional.

04 / ABOUT
Engineer on the ground, pilot in the air.
I'm a software engineer with 10+ years of building digital products. I co-founded indigo online, a Holacracy-run agency in Bern, where I ship full-stack apps for clients like SBB and Swisscom — and help design how a self-organising team actually works day to day.
Alongside that I'm doing an MSc in Applied Information & Data Science at HSLU — turning a long-standing obsession with clean data and honest models into the next chapter.
And most good weekends I'm in a glider: no engine, no noise, just reading the air and managing energy. It rewired how I build — brief the plan, trust the instruments, keep a margin, always leave yourself an out.

05 / FLIGHT DECK
Take the controls
Hold to climb, release to sink. Ride the signal corridor and scoop up data points. Drift outside it for more than 1.5s and you lose the signal — same margin-for-error thinking as real soaring.
