Freelancer profile translated to English.

Description

I bring structure to complex software landscapes.

Many companies struggle with historically grown systems, unclear responsibilities, and stalled projects. This is exactly where I come in.

As an experienced IT Project Manager, I support companies in successfully implementing complex software projects – from analysis and structuring to stable implementation in operations.

My Focus Areas:

Management of complex IT transformations and migrations
Stabilization of critical systems and operational processes
Structuring unclear requirements and system landscapes
Coordination of multiple teams, service providers, and stakeholders
Introduction of clear processes and transparent decision-making bases

I particularly enjoy working in demanding environments where many parties come together and technical as well as organizational challenges intertwine.

Typical Results of My Work:

Projects become manageable again and achieve their goals
Systems run stably and comprehensibly
Teams collaborate in a more structured and efficient manner
Risks are identified and reduced early on

I combine technical understanding (including system architecture, Java-based systems, integrations) with strong project management and a clear focus on the essentials.
