Engineering, Programming, Commissioning – Your Automation Project in Experienced Hands

Over 12 years as a PLC programmer, with international experience integrating automation technology into new and existing plants.

Specialized in Siemens PLC systems, I support projects from concept through final customer acceptance. My strength: on-time, precise commissioning of complex production lines – worldwide and across industries. Two core areas today: commissioning of new production lines – in Saar-Lor-Lux, Switzerland, across the DACH region and worldwide – and retrofit of existing controllers: migration of S5 and S7-Classic to S7-1200/1500 with TIA Portal, HMI retrofit to WinCC Unified, plus reverse engineering when only an online snapshot without symbols remains.

What Excites Me About Automation Projects

I started as an electronics technician, then studied electrical engineering and automation, and spent nine years leading international projects at Köhl Maschinenbau. What always fascinated me: The moment when a system runs for the first time – and everything works. When mechanics, electrics, and software interact perfectly, and individual components become a functioning production line.

Today, I help companies achieve exactly this moment: Reliable, on schedule, and without unpleasant surprises. Whether PLC programming, safety concepts, or worldwide commissioning – I deliver solutions that perform in operation. I focus on structured programming, complete documentation, and transparent communication with all project stakeholders.

What I offer today: combining classical automation with edge technology and AI – for more efficient production facilities. AI-assisted engineering is an integral part of my work: groundwork such as I/O lists and symbol tables is ready earlier, PLC programs and WinCC Unified visualizations are tested more thoroughly, and the documentation is produced along the way. Decisions and approvals stay with me. For plant operators I implement AI-assisted data analysis: plant data access via OPC UA, dashboards, fault and downtime analysis, reporting. AI evaluates the data read-only; the PLC stays deterministic. Complemented by software development in Python and TypeScript and container technologies.
