About Simon Robert

You want to integrate AI into your product - not as a demo, but production-ready. That's exactly what I do.

I'm Robert - AI Engineer, Physicist (MSc), and former SaaS founder with years of experience in backend development. Before building AI systems, I developed complete SaaS products from scratch - touching every layer myself. This isn't a nice-to-have: Anyone wanting to bring LLM pipelines or RAG systems into production needs someone who also understands the infrastructure beneath them.

I deliver LLM integrations, RAG systems, multi-agent pipelines, and AI-powered backends. One example: For a RegulationTech startup, I developed a pipeline that extracts tax and social security law from government PDFs and translates it into executable calculation logic. Six weeks for the German market, then a weekend per country. A seven-figure funding round followed.

Over 20 projects, including for banks, fintechs, and research institutions. At 2pi IT Solutions, a small team stands behind me, scaling up as needed.

Write to me with your project - I'll honestly tell you if and how I can help.
