Currently Chief Technologist at Novatec, he focuses on practical implementation over abstract theory. Whether that means untangling manual instrumentation for Java and Python or analyzing system traces in Jaeger, he cares about what actually works in production. He frequently maps out developer workflows, particularly around making Spring Boot play nicely with Docker and Kubernetes. His talks usually skip heavy slides in favor of live demonstrations, walking through exactly how to use tools like OpenTelemetry and Testcontainers. ## Past Sessions ### World Congress 2025 路 July 9, 2025 Berlin, Germany - [OpenTelemetry Hands-On - Manual and Automatic instrumentation for Java and Python apps](https://www.wearedevelopers.com/events/world-congress-2025/sessions/810-opentelemetry-hands) 路 120 min - [What's (new) with Spring Boot and Containers?](https://www.wearedevelopers.com/videos/1514-what-s-new-with-spring-boot-and-containers) 路 30 min 路 馃帴 Watch recording ## Videos - [What's (new) with Spring Boot and Containers?](https://www.wearedevelopers.com/videos/1514-what-s-new-with-spring-boot-and-containers) 路 Eva Panadero, maeddes ## Links - [X](https://twitter.com/maeddes) - [LinkedIn](https://www.linkedin.com/in/matthiashaeussler/) - [GitHub](https://github.com/maeddes) - [Blog](https://www.novatec-gmbh.de/)
