Built forreal use.
I’m Fynn Auerbach, based between Zug and Aarau, studying at the Informatikmittelschule in Aarau.
Most of my projects happen alongside school. I usually start with one concrete idea that stays with me for a while and keep at it until everything fits together cleanly — from the backend through the infrastructure to the interface.
In the end it just needs to run reliably, with nothing I’d be embarrassed about later.
How I work.
Three things I actually try to stick to — how I plan, how I use AI, and what I do with the things I pick up along the way.
- I
Plan to the size of the problem.
Small tools: I ship a rough version and clean it up while someone is already using it. Bigger projects get the opposite treatment — I sit down first, write an actual brief, sketch the architecture, sometimes a full spec, so future me does not have to guess what past me was thinking.
- II
AI as leverage, not a crutch.
I started coding years before AI was actually useful, so I know how to get to a working version on my own — which tool to reach for, where to start, what to ask. When I use AI, I know how to prompt it, what context it needs, and where it tends to break down. I can feel the difference between models and pick the one that fits the job. It makes me faster; it doesn’t do the thinking for me.
- III
Pass on what sticks.
I’ve learned a huge amount this way, and people around me who are into this stuff tell me they pick up things from me too — often things that don’t really come up in school. I like that part. You understand something properly once you try to explain it out loud.

About.
My curiosity for code sparked at age 10 with Scratch, but I quickly sought more creative freedom. That drive led me to Unity and C#, where I began building systems that could truly think and act. What started as a childhood hobby has since become a craft — from simple scripts to architecting full-stack applications.
The highlight of my middle-school years was dedicating over a year to an autonomous model car — a blend of Arduino, Raspberry Pi and neural networks. That project proved to me that passion and persistence can bring any idea to life, no matter how complex.
Today I’m channeling that same focus into an AI contract analysis project while building my own small SaaS tools on the side. My work spans the stack — from designing databases in Supabase to pixel-perfect frontends in Next.js. Complex problems are where I learn the most.
