Software Engineer at RTL Technology GmbH, modernizing data integration with Kotlin services and Apache Kafka.

Germany

Message

At RTL Technology GmbH, I develop and maintain integration solutions that enable reliable data exchange across the RTL Group. I contribute to replacing the legacy BizTalk platform with an Apache Kafka-based architecture.

I develop Kotlin integration services with Spring Boot, using microservices and modular monoliths with Spring Modulith. I also build bidirectional data flows between CRM, advertising, and payment-related systems using Apache Kafka and Kafka Connect.

At 1&1 Mail & Media Applications SE, I developed and maintained microservices for the netID Permission Center and an internal Permission Center portal. I also created shared Java libraries and backend services used across Mail & Media products.

Earlier, as a Working Student in Software Test Automation at 1&1 Mail & Media Development & Technology GmbH, I designed and implemented automated acceptance and integration tests using BDD, Cucumber, and JUnit. I also built automated test solutions using FitNesse and Robot Framework.
