Summary
👤
Senior🎓
Top SchoolJakob Stemberger is an IT Solution Architect with 13+ years of hands-on experience designing and migrating large-scale Java and SOA/EDA systems for enterprise and industrial clients. He has led architecture and technical delivery across payments, gaming, automotive and logistics domains, specializing in JEE, Spring, Quarkus, cloud-native migrations, Kubernetes and messaging platforms like Kafka and RabbitMQ. Jakob combines deep legacy-modernization expertise—having migrated monoliths to microservices and J2EE to Quarkus—with practical automation work to accelerate repeatable monolith-to-microservice transformations. He has been principal architect for high-throughput services such as payment and wallet systems and assessed safety-critical autonomous transport software for manufacturing. Based in Karlsruhe, Germany, he pairs a developer-first mindset (Java, C#, C++, scripting) with trainer experience, which helps translate complex architectures into executable team practices. An early-career background in C++ banking libraries and even vocational experience as a bike mechanic hint at a pragmatic, systems-oriented approach to problem solving.
