Backend Java Developer | Android Developer
T-Systems International GmbH
- Improving and developing new features for the software which runs on the onboard units of different public and private transportation companies vehicles throughout Germany. One of the major features implemented was to extend this application to provide information for a Web UI (based on Vue.js) which will run on separate Android devices or on newer versions of OBU equipped with Android backed touch screens.
- For smaller customers, who are not willing to purchase the full software package, there is an Android application, which has all the major features of the onboard unit application. When needed I’m doing the feature implementation in the Android app as well.
- As a member in a scrum team, I do solution proposals, development, code reviews, mentoring and assist other team members on their current assignments.
