Jonas supported us in the subproject V2X (Vehicle-to-Everything) within the program “5G-Bavaria Testcenter“ as a freelance software developer. In doing so, he implemented the frontend application of the subproject using NextJS. We were particularly satisfied with the speedy implementation, good documentation and test coverage of the written code. To this day, we are thrilled with the stability of the developed application. In addition to the implementation of the frontend, he also advised us on the integration of CI/CD pipelines and pointed out optimization potentials in agile working with tools like Jira and GitLab. His open and pragmatic way made communication with the backend teams very easy and enabled fast integration of new features. He also mentored junior developers in an exemplary manner and enabled them to continuously develop themselves through knowledge transfer and mentoring, so that they could take over the project independently after his departure. We really appreciated working with Jonas and are happy to recommend him!
