Projects & references

After more than 25 years in the project business in an international environment, I look back on numerous successful projects and satisfied customers – from wastewater plants in Switzerland to industrial plants overseas.

Focus areas

Project areas

Infrastructure & energy

Critical infrastructure and energy: public lighting (EKZ) and data centres (Equinix) – with WinCC OA, TIA Portal, PCS 7 and OPC UA.

Logistics & sorting

Software development for parcel and mixed-mail sorting plants – including for DHL Express and Swiss Post.

Wastewater & WWTP

Wastewater plant projects, stormwater tanks, wastewater heat recovery and safety controllers throughout Switzerland.

Steel & industrial plants

International commissioning of steel and industrial plants in Europe and the Americas.

Retrofit & migration

Modernization of existing plants and migration of legacy controllers (S5 → S7 → TIA) and from WinCC Advanced to WinCC Unified.
