Hello! 👋 I am Jan

I am a freelance AI consultant. I have been working in AI since 2012, long before the ChatGPT boom, including a decade of research and engineering at the German Research Center for Artificial Intelligence (DFKI). I understand how the technology works under the hood, beyond cloud APIs.

What I offer

• AI Engineering: Custom AI applications, especially chatbots and assistants built on large language models, including model training, evaluation and integration into your systems. I hold a PhD in AI and chatbots and have been building chatbots since 2017.
• AI Infrastructure: Sovereign, self-hosted AI infrastructure with open-source models (on-premise GPU servers, local LLMs, API access), so sensitive data never leaves your organization.
• Project Leadership: Leading AI projects from requirements analysis through prototype and evaluation to handover into production, backed by 7 years of software development and experience leading teams.
• AI Training: Hands-on, project-based training in which your team learns by working on a real AI project, so it can run the solution on its own afterwards.
