I'm currently working as a full stack software engineer in the "Mobile Self-Checkout" team at REWE digital. Our team provides different backend services and corresponding frontend SDKs to include a Scan & Go feature in various apps of the Rewe Group.

• Kotlin on frontend (Android, KMP) & backend
• Microservices with Spring Boot, WebFlux, R2DBC
• Git, Gradle, GitHub Actions & GitLab CI/CD
• Kubernetes, Rancher & Helm

For 6 and a half years, I worked on automotive infotainment systems as a Java software engineer in the framework team at e.solutions, a joint venture of Elektrobit and CARIAD. Part of our responsibility as framework is to provide bridging components which allow different car systems – speaking different protocols – to communicate with each other. We also offer highly configurable IPC mechanisms, several code generators and system-wide tracing libraries.

• Java 8, Kotlin, python
• QNX, Linux, Android
• REST, OpenApi/Swagger, RxJava, JSON
• JUnit 4, Mockito, Robolectric
• Git, Perforce
• CMake, Gradle
• eclipse, IntelliJ/Android Studio
• BitBucket, JIRA

I developed several mobile applications for the Android platform. In the process, I improved my knowledge about the eclipse IDE & Android Studio and used version control systems like SVN and Git. I know my way around the Android API and the Android design guidelines and I founded my own business to sell these apps on the Google Play Store.

I helped students in their 2nd semester to understand the "Algorithms I" course (sorting algorithms, data structures, graph algorithms etc.).
