About Andre

I am a Requirements Engineer, Product Owner, and Software Designer with a focus on the digitalization of complex processes. My focus is on the structured collection, analysis, and specification of requirements to align software solutions clearly and purposefully from the outset.

With technical expertise, methodological certainty (e.g., agile requirements engineering, model-based specification), and a deep understanding of organizational and development-specific processes, I want to support companies in implementing digitalization projects efficiently, practically, and sustainably – whether in the conception phase, as external support in the project team, or as an interface between the business department and development.
