You wanted the boring facts? Here they are. Roughly two decades, mostly as a one-man-army, in reverse order.
Litora-Nova — since late 2024. Building your company of 2028.
BS-Inventory — 12.2024–03.2025. QR-code inventory management. Intranet-only, internal app.
My-Zanzibar-Home — Q1 2024. A real-estate platform for a friend. Fully AI-designed, AI-texted, AI-pictured.
nerd: I still had to code it — but it was already nice. :)
Burnout. ...
FreakFunnels — Q2 2023. An AI-assisted website & funnel builder. Voice-to-Website (back then, context was the limit!). Developer-focused, Vuetify-based styling and grid. In-app model training, usable by non-coders. An AI playground to test different models. A training-data manager.
nerd: At that time there was no AI playground yet — I had to build my own. To even test microphone plugins, I built a little "voice in any language → English text" tool. I was living in Africa then, and the Whisper API turned even mumbled Swahili into clean English. That actually helped me a lot. :)
Demokratischer Widerstand — since 06.2020. News publication.
booking.mymedisyn.ch. A booking platform for medical examinations of all kinds.
nerd: even this one, one-man-army! It survived Corona with 99.9% uptime. I wrote every line by hand — still pre-AI-coder times.
mobile-truck-service (not the real name).
nerd: The main supplier had no API, but we needed one. Their answer: "there's a CSV download, it's always current." Fine — good enough for me. After two weeks they built us a proper API, because the constant CSV downloads from my "emulated" API were driving them nuts. Nothing is unsolvable. :)
smunch. Food by subscription, done sexy. A plan for the office, full freedom for the employees: pick your meal, tax-advantaged, fully integrated into payroll. APIs to all the big German payroll systems (DATEV, Sage, ...), plus predictions. METRO-Techstars Accelerator.
nerd: Shivram actually just asked me to build him a Google Form in 3 weeks. Okay, I needed 4 — but for a fully working MVP. :)
shyftplan. Still the German market leader in shift planning. I built the MVP in 6 weeks.
hellocare. Booking care, simply. PRO7SAT1 Accelerator. Exit.
cleanagents. Acquired by Helpling. Here I only worked as a developer.
orderlift. A simple webshop with simple onboarding via CSV upload, POS, and so on. A 3-day hackathon — we became one of 5 in the YOU IS NOW / ImmobilienScout Accelerator.
nerd: We deliberately did NOT present in fullscreen, so the jury could see the terminal behind the browser. Then: CSV upload. Terminal rattles... products appear... The jury told me later: that was the moment. :)
Mediengestalter für interaktive Digitalmedien — 2009–2012 (media designer for interactive digital media).
nerd: I argued so much with some of the teachers — and was usually right, because I already had years of hands-on experience — that after 6 months they freed me from class. :)
Computer-science studies — 2007–2009. The beginning was absolutely no fun. Interesting, at least — but later... I never wanted to build or design computers. They're already here — just teach me how to use them. So I skipped it.
nerd: the prof was teaching us how ttys connect — so mid-lecture I used
writeto land text straight on his tty. It popped up live in his session, on the beamer. The exact thing he was explaining. He laughed. :)
Some real work — 2001–2007. Advertising agency and sign-making. Ladders and wrenches included — there are still a few signs around Berlin I helped install. But also my first HTML projects.
First invention — 2001. With some friends I kind of invented/designed a continuously variable bicycle gear shift. Nothing came of it — I'd have needed 50k, and I didn't want to take the 1M I could have had.
Highschool — until 2001.
nerd: A bit of trouble, after I made a whole computer room go a little crazy. Even more trouble once the teacher found out I'd just applied last lesson's material in a slightly more creative way. :)
Down here we were still running stable Microsoft systems 🤣 — they called it DOS.
My first computer was a C64.
Favorite game: Maniac Mansion.
nerd: for the youngsters — like GTA 5: multiple playable characters, different endings. Back in the '80s. :)
