Raffael Herrmann_
IT-Magician (Allrounder)
IT is my passion and has always fascinated me. Even in my school days, I worked a part-time job in a software company and developed small projects there. This was followed by an apprenticeship, studies and a career in consulting and in-house positions with various focal points. Among others:
In addition to the above, I think outside the box every day and am enthusiastic about other topics such as web development or embedded development with Arduinos / ESP32. If something can be automated, I automate it!

In addition to the skills mentioned above, I have gained experience with many other languages, tools and applications (and have implemented at least a few projects with each of the following technologies):
The SAP CPI Dashboard is a web-based tool (website) that can be used to check various parameters of a SAP CPI instance. This ranges from CPU, RAM and hard disk utilisation, message volumes and object comparisons to insights into passwords and user data.

QRCoder is a .NET class library that I wrote from scratch in C# that enables the creation of QR codes. With over 18 million downloads of the associated Nuget package, QRCoder is one of the most popular .NET libraries in its class. The project was born in 2013 out of an interest in how QR codes work. And if you want to understand a software system, what could be more natural than implementing it yourself?

The iflow-plotter is a command line tool written in NodeJS. The iflow-plotter can be used to convert SAP CPI IFlows into diagrams / graphics. The exported graphic files can in turn be used for documentation purposes.
