Hello, I’m Hartmut!
I build the bridge from vision to running real-time applications.
My mission is to help companies design and implement thoughtful and future-proof stream processing architectures. This enables them to not only make faster decisions but also create a real technological advantage.
What you can expect from me
Proven Architectures
Together we design Kafka Streams topologies that not only look good on paper but are also reliable and scalable in production use.
Enablement instead of dependency
Through technical mentoring, code reviews, and pair programming, I share my knowledge and sustainably strengthen your team’s competencies.
From idea to go-live
I support you throughout the entire lifecycle: from requirements analysis through implementation to deployment strategies and monitoring for maximum operational reliability.
Recognized Expert
As an active member of the Kafka community and recognized speaker at conferences and meetups, I always bring the latest insights and best practices to your project.
Pragmatic Solutions
I don’t build castles in the air, but deliver concrete, actionable recommendations and actively support your team in implementing mission-critical applications.
Focus on business goals
Technology is only a means to an end. My focus is on understanding your business goals and supporting them through tailored real-time solutions.

I initiated the open Kafka Streams Topology Design (KSTD) standard to help teams visualize and communicate their architectures more clearly.
Kafka Streams Architecture & Design From designing complex topologies to implementing robust and scalable real-time applications.
Stream Processing & System Modernization Analysis and optimization of existing architectures as well as development of new, high-performance solutions for critical business processes.
Technical Mentoring & Coaching Knowledge transfer and enablement of developer teams through targeted coaching, pair programming, and code reviews.
Deployment & Operations Consulting on best practices for deployment strategies, integration testing, and monitoring to ensure reliability in operation.
Talks
Sharing knowledge is my passion. As a regular speaker at international conferences and meetups, I pass on my experiences and actively contribute to the Kafka community.
