Summary
Technical project manager and product owner for complex software development and connected product programs. For more than ten years, I have been steering projects at the intersection of business, development, and architecture — including for Bosch, Miele, and Vorwerk.
My strength lies where program goals and technical delivery start to drift apart: I bring requirements, architecture decisions, and delivery capability back into line — across teams, locations, and external service providers.
Focus areas: technical project and program management, product ownership, requirements and stakeholder management, test and quality management, IoT, and connected products.
I am looking for projects in technical project or program management as well as product owner roles — remote or hybrid, across Germany.
