Freelancer profile translated to English.

Description

Brief information:

In my professional SAP career to date, I have been able to gain national and international project experience. The multifaceted tasks always required an intensive engagement with the relevant business management topics as well as with the programming-technical concerns and requirements in the SAP environment (object orientation, class and data modeling, software design as well as interface and transaction programming and surface development, among others). Currently, the topics Hana DB, S/4 Hana, OData and Fiori/UI5 are also very relevant.

Directly at SAP AG and SAP LGD in Walldorf, I had the opportunity to work in various international projects, e.g. IS OIL, SSCR (gas station solution), APO (customer project), SAP Bankanalyzer, CRM (standard + customer project), SRM (standard + customer project), and also to support in various customer projects, e.g. in the SRM, SAP Retail and EACM environment and most recently in the financial environment (FI).

My comprehension and analytical skills enable me to quickly familiarize myself with new and complex topics. Due to the nationally and internationally changing projects, it is a matter of course for me to work with colleagues from different cultural backgrounds. I am fluent in German and English as project languages.

In order to be able to work independently of the customer systems with the new technologies (Hana DB, CDS Views, Fiori, etc.), I have been renting an S/4 Hana system (version 2021) since 2022. This allows me to work with my own settings, configurations and developments, but also with the Eclipse development platform.

Project:Development of a role concept for the Fiori Launchpad

For example, the new concept of Spaces + Pages but also the classification of users into e.g. 'normal' users, key users and administrators.

The configuration of the Fiori Launchpad as well as the associated apps, e.g. Notification, MyInbox, is to be checked and the function of these is to be guaranteed. A corresponding role concept for the apps in the Fiori Launchpad was also to be created.
