Über Marvin
Hi,
my name is Marvin and I’m a Backend Engineer working with modern technologies like Kafka, Java, Kotlin, GraphQL, mongoDB, SQL (and many more) in a microservice-based architecture. I like staying up to date and enhancing my skills day by day and I'd be super happy to do so for you.
I'm an experienced developer, worked in many agile, cross-functional teams for Gorillas, REWE digital, commercetools, and more. Creating concepts, RFCs, deploying features, sharing knowledge, running workshops, as well as mentoring other developers, are just some of my strengths.
I’m truly passionate about my work and always eager to connect with other developers. I enjoy all aspects; analyzing new technologies, improving existing solutions, or working on new features. Also, the discussions about the best possible practices and letting ideas flow is super fun.
