Hartmut Armbruster
Software Engineer, Content Creator
Berlin, Germany
Summary
🤩
RockstarHartmut Armbruster is a Berlin-based software engineer and content creator with 11 years of experience designing and delivering high-throughput, real-time streaming systems. He’s a Kafka and stream-processing specialist who has driven architecture and implementation for retail, transport, finance and public-sector projects—transitioning legacy batch systems to elastic, event-driven platforms. Hartmut blends deep technical craft (Kafka Streams, distributed databases, Kubernetes) with a talent for clear communication, creating video courses and visual explanations that elevate engineering practice. He has led large cross-border teams and mission-critical programs, from HSBC’s global trade platform to Deutsche Bahn passenger systems, demonstrating both technical leadership and operational delivery. Less obvious: he pairs hands-on implementation with pragmatic cost and performance wins (e.g., dramatic reductions in re-indexing time and hosting costs), making complex systems simpler to operate.
