Senior🎓
Top SchoolHolger Hoffstätte is a Senior Software Architect and problem solver with over 30 years of hands-on experience and a recent focus on distributed systems, networking, and building scalable, reliable software infrastructure. He blends deep systems-level knowledge—frequent open-source and occasional Linux kernel contributions—with pragmatic consulting experience across startups and large enterprises, including roles at Elastic, MuleSource, and NTT DATA DACH. Holger’s boutique consultancy track record shows a knack for fixing “Hard and Complicated Problems™” in messaging, low-latency systems, JVM performance, and distributed storage, while his Gentoo contributions underline practical expertise in build systems and package reliability. A strong proponent of evidence-based engineering, he designs evolvable architectures and migration strategies that balance performance, operability, and long-term maintainability. Based in Lindlar, Germany, he combines specification-level work (OSGi, DDS) and production-grade implementations, making him equally comfortable in research, R&D, and mission-critical delivery.
