AI products, in front of real people.

“Keep the weird. Skip the filler.” Someone in my comments asked for a filter for AI-written posts on LinkedIn, X and Reddit, and my agent built it overnight.
It runs on Cloudflare and uses Clef, Cloudflare’s typed decision model, so each check comes back as a structured verdict, fast and at low cost.

RoomRush
I needed a flat in Munich, so I built a tool to find one. It found me one.

My first self-initiated product, built for my own flat hunt in 2023. I launched it alone and did everything from the code to the marketing. People loved it.
The unit economics made it too expensive to run as a business, so I stopped it.
What it taught meWhen to stop: a product people love still has to pay for itself.
How they got to people.
The same few moves, learned one product at a time.

Then it comes back to work.
At Beyond Presence I own the creator and call platforms behind our real-time avatars and Managed Agents, frontend and backend, and I shipped the integration that sends an avatar into a Zoom or Teams call, on top of a third-party meeting service.
What the lab taught me about selling, I bring back to work: I’m automating our go-to-market with n8n and AI agents wired into Slack.
The habit is older than the lab. In 2022 I was picked for AGORA, an entrepreneurship talent programme run by DAAD and the Strascheg Center at Hochschule München, working closely with startup co-founders, and I was an active member of TUM.ai, Munich’s student AI initiative.
