Back to original languageAbout Michél
You want to use AI in your company - pragmatically, in compliance with data protection regulations, and without buzzword projects. That's exactly what I'm here for.
I develop AI solutions for municipal utilities, energy providers, and SMEs in the DACH region - from the initial strategy to productive application. My focus: LLM applications, RAG systems, and AI agents based on your own data - including the appropriate AI infrastructure and AI governance in line with the EU AI Act.
What sets me apart from pure consultants: I build myself. As Team Lead Software Development and Deputy Head of IT for a municipal utility, I know the regulated reality not from slides, but from day-to-day business - tight budgets, established IT, data protection, and works councils included. I don't deliver PowerPoints, but software that fits your landscape.
See for yourself: My own AI concierge runs on my website[[ michel-trenkner.de ]]- an agent system that guides you through project onboarding and directly captures your use case. Live, not as a screenshot. This is exactly the quality I build for you.
Typical projects I undertake:
- AI Strategy & Use Case Assessment
- RAG Chatbots & Knowledge Assistants on Own Data
- Agent Systems & Multi-Agent Workflows
- AI Infrastructure (Model Integration, Vector DB, Self-Hosting/EU Cloud)
- AI Governance & EU AI Act Readiness
- Full-Stack Implementation (Next.js, TypeScript, AI SDK)
Let's talk about your specific use case.
