IT-Consultant for SAP ERP and S/4HANA

About me

About me

I'm an IT consultant at the top consulting company called adesso orange - the SAP powerhouse of the adesso Group.
My focus is material management and development in the backend as well as interfaces with SAP and third-party systems.
Of course, as is the case as a consultant/developer on the job, I also deal with other topics, e.g. if this is necessary in a project.

My interest in everything to do with ERP developed during my studies in business information systems in compulsory and elective modules and as an ERP tutor. The passion at the beginning of the job since 2019 also leads to maintaining my own wiki in my free time in order to save the knowledge I have acquired for myself, but also to be able to share it with others.
