Hi! I read every note. Feedback on a case study is especially welcome, the honest kind.

I'm Tobias. I help teams turn requirements into clear decisions, crafted UI and design systems that scale. With AI, I take ideas straight into interactive prototypes in code. Web, iOS and Android, with a human touch.

How I work
What I bring to every team, and where you can see it in my work.
AI does the busywork. People make the decisions.
Design to CodeCount value, not clicks.
Invia · Offer BoxMake the customer's next decision obvious.
Invia · Flex TicketEvery design decision should be easy to explain.
Esports platformOne decision at a time.
Invia · Price GuaranteeHonest beats pushy.
"From restaurants to esports stages to booking funnels, I learned the same thing: people decide better when the choice is clear and fair. So I keep the important choices obvious, and I let the test decide."
Fun
New tools get tested on real use cases first. Each one comes with a tutorial, so you can build it too.

About
I started out in restaurants, studied science, and called esports matches live before I moved into UX. Each stop still shows up in how I work: I read people quickly, I trust data over gut feeling, and I explain complex things in plain words.
Today, with six years in UX, I work as a freelance UX/UI and product designer in Berlin. I design products across B2B SaaS, travel and gaming, and I build the systems that keep them consistent.
Notes
Say hi, give feedback on a case study, or tell me what you're building. Notes show up here after I've read them.
