Sept 2005 to Jan 2008Apprenticeship - CS Expert for Software Dev. (IHK)

Full time Trainee @ Siemens AG - Brunswick, Germany

After I finished school, I did an apprenticeship as an Computer Science Expert fpor Software Development at Siemens AG. The training was carried out within the company and also partly at the vocational school. After two and a half year I was able to graduate and thus also succumbed to my technical college entrance qualification.

Jan 2008 to Sep 2012Application Developer - Computer Science Technician

Full time Employee @ Siemens AG - Brunswick, Germany

With the completion of my training as a computer science expert, Siemens AG offered me a full-time job as an application developer and computer service technician. My main task was the development and further development of loading tools for the software of railway interlocking systems. With the help of the programs I developed, current software versions were flashed onto the interlockings. In the development I worked exclusively with the programming language C++. The QT framework was also used to create a visual interface, which is where I first encountered the signal slot principle.

2010 to 2011Media Informatics (online studies)

Part time Student @ Ostfalia university of applied science - Wolfenbüttel, Germany

In addition to my job at Siemens, I started studying media informatics. Unfortunately, I realized very quickly that the course contained hardly any knowledge worth mentioning that I did not already know from my training as a computer science expert. So I took everything that was relevant to me with me, such as the media design courses. I also learned the programming language JAVA for two semesters.

Oct 2017 to May 2018Frontend Developer / Web Developer

Part time Employee @ Deutsche Messe Interactive GmbH - Hanover, Germany

Since my business partner is slowly withdrawing from the joint company to retire, I made the decision in 2017 to look for a job as a developer again. I found a part-time job at the subsidiary of Deutsche Messe AG. Here primarily my knowledge in PHP and web development was asked. Together with a team, I maintained Deutsche Messe AG's exhibitor management system and implemented requirements for further development. Furthermore, with my experience in Wordpress and web development in general, I was able to contribute a lot to consulting for future projects. Unfortunately, the subsidiary was closed very suddenly due to the decision of the parent company, Deutsche Messe AG. As a result, Deutsche Messe Interactive GmBH ceased operations in mid-2018.

Jul 2018 to Dec 2020Senior Frontend Developer

Part time Employee @ multi-media-managmeent GmbH - Hanover, Germany

After the sudden business closure at my previous employer, I looked for a new part-time job. I found this at multi-media-magement GmbH. Here I was hired to support the development team as a senior frontend developer. Since the company was in a strong growth phase at that time, my area of responsibility changed very quickly from working as a developer to working as a technical product owner. However, I came into contact with the Javascript framework Vue.js and was able to learn a lot about the workflow with Javascript-based web applications. As a technical product owner, I received stakeholder requirements and communicated and evaluated them with the management and the development team. I really liked the work as a connecting and mediating element of the workflow.

Aug 2013 to nowPlatform Administration, Maintenance and Development

Project IFARlink @ German Aerospace Center (DLR) - Cologne, Germany

During my work as a partner at the internet agency Kähler, I was able to win the German Aerospace Center (DLR) as a long-term customer. A social network based on the CMS Joomla was developed on behalf of DLR. Furthermore, the portal has been expanded to include several individual technology databases. In recent years, a separate app has also been developed, which is available for iOS and Android. The social network platform is managed and maintained by me and in consultation with the DLR and other space organizations such as NASA, NRC, JAXA and many more, it is constantly being further developed. The project has been running since 2013 and is renewed on an annual basis. Every year, a different space organization provides the chair man - accordingly, new ideas and suggestions for further development are constantly being generated. You can find out more on the relevant portfolio page.

Jan 2013 to nowPartner, Web Developer & Web Designer

Partner @ Internet Agency Kähler - Isenbüttel, Germany

I had the opportunity to join the internet agency Kähler as a partner. Now that I've been able to gain professional experience at Siemens AG for a number of years, I've decided to resign and take the next step in my career. At the internet agency Kähler I was able to perfectly combine my skills as a software developer and my newly acquired knowledge in the field of media design. I am able to handle projects of various sizes and have a lot of variety. My main task is to look after customers, create and design websites and develop individual requests. I now run the internet agency part-time if required. Over the years I've taken on a few jobs on the side, as this gave me the opportunity to work more in a team again.
