I am a passionate software engineer, working as a Senior Consultant for Holisticon AG in Hamburg, Germany. I have ~25 years of job experience and spend most of my time implementing individual software solutions for medium and large customers. These solutions are mostly non-trivial distributed (microservice) systems, using event-driven architecture, DDD and CQRS/ES. Whenever I have the free choice, I choose Kotlin as my programming language, Camunda for process automation and axon-framework/axon-server for event-sourcing. I love sharing my knowledge and I am an author or contributor to several open-source libraries and a regular conference speaker.
