What have I done?
Software Consultant at INNOQ
2016 - present
At INNOQ, I work closely together with customers to develop custom software.
The most important question to me is not how to solve a specific problem, but making sure that we are solving the right problem.
Based on this knowledge of the core domain, we can decide on the best architecture for our system and decrease complexity so that we can maintain and evolve the system over time.
My responsibilities as a consultant include architecture discussions, backend development, web security, and user interface conception and implementation. I also work iteratively with customers to identify problems with the user experience and improve them.
Research Assistant at Heinrich Heine Universität
2011 - 2016
During my studies, I worked with the STUPS research group and in conjunction with industry partners during the course of the ADVANCE project to develop the ProB tool chain for verifying formal specifications.
My work mainly consisted of developing a Java API written in Java and Groovy for interacting with ProB. I also was able to contribute to the kernel of the application which was written in SICStus Prolog.
Community
In 2011, I started attending the rheinjug regularly and volunteering. In 2014 I became an official member of the organization. I also have helped organize the Clojure Düsseldorf and Lambda Düsseldorf meetups.
Since 2017, I have been organising and moderating the EntwickelBar unconference as well.
