You want to implement AI in your company, pragmatically and in compliance with data protection regulations. That's exactly what I'm here for.
I develop AI solutions for utility companies, energy providers, and SMEs, 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 differentiates me from pure consultants: I build myself. As Head of Software Development and Deputy Head of IT at a utility company, I know the regulated reality not from slides, but from day-to-day business, tight budgets, existing IT, data protection, and works councils included. You won't get a PowerPoint, but software that fits into your landscape and goes into operation.
The best way to convince yourself: On my website, my own agent system is running, which guides you through project acquisition and directly captures your use case. Live, not as a screenshot. This is exactly the quality I deliver for you. Under **Services**, you will also find ready-made AI systems and software solutions, quickly deployable and adaptable to your data.
Typical projects I undertake:
- Ready-made AI systems & AI agents — deployable, on your data
- RAG chatbots & knowledge assistants
- Agent systems & multi-agent workflows
- Interfaces & integrations (APIs, MCP) into existing systems
- AI infrastructure (model connection, vector DB, self-hosting / EU cloud)
- Individual software solutions (full-stack, Next.js / TypeScript, AI SDK)
- AI strategy, ROI, use case evaluation & EU AI Act readiness
Let's talk about your specific use case.
For larger projects, I'm not alone: with two other specialists, we form a well-rehearsed trio. This allows us to handle complete infrastructure projects, coordinated, from a single source, from architecture to operation.
