I come from the German Rhineland and am now proud to call the beautiful port city of Hamburg home. I’m an eternal optimist and a keen traveller.

I have more than 20 years‘ experience in the SAP software development business. I learned my skills first-hand, spending four years as a software developer in the FI-CA team at SAP.

I then worked on projects for consulting firms all over Germany. These included challenging long-term projects for various big corporations.

I started working as an independent SAP technical consultant and software developer in 2015. My strengths include solving my clients‘ problems quickly and thoroughly and explaining the solutions available clearly and in full.

„I’m only happy with a job when my clients are happy too!“

My mission is to find the right solution to suit each individual client’s needs.
