Manuel Treutlein

Manuel has this to say about his time at OXYGEN TECHNOLOGIES:

I did a three-month internship at OXYGEN TECHNOLOGIES and the time absolutely flew by. I worked in software development while studying for a degree in computer science in Karlsruhe. My tasks were very interesting and I was able to gain an insight into every part of the business. The support was amazing. They treated me as a fully fledged developer. I was able to take on responsibility and work on production code. All in all, the only thing I can say is: thank you for an incredible time and all the things I learned.”

Manuel Treutlein is studying for a bachelor’s degree in computer science at the Karlsruhe Institute of Technology (KIT), and worked as an intern in the software development department from February to April 2020
