Overdigital is where I build with AI in public. Not as a user, but as a builder — running local large language models on an RTX 5090, wiring multi-LLM pipelines into real products, and writing about what I learn along the way.

Current things I’m shipping: Showspring, an end-to-end AI production studio where four LLMs pitch every episode and one button ships it to YouTube; The Doodle Cast, a long-running AI-animated talk show authored entirely by a production agent; WillWin, nightly multi-event forecasts on a 32B local model; and Bulb, where Claude, Gemini, and Grok debate startup ideas in parallel. All four run on the same home-lab infra.

The day job is a technology-executive seat with two decades in media, software, and digital infrastructure — streaming video platforms, interactive advertising, content delivery — most of which has informed the way I now build AI tools that have to actually ship.

I’ve served on the Streaming Video Alliance Board of Directors since 2018, contributing to industry standards around OTT metadata, CMAF, and next-generation video formats. I hold a US patent for replacing content surfaces in video (US 10306286) and was named to the Cablefax Digital Hot List in 2014 and 2015.

I write in English and German, and I’m equally comfortable talking about transformer architectures and the business models that will actually make AI sustainable. If something here sparks a conversation, reach out.
