Summary
👤
Senior🎓
Top SchoolJeroen Rinzema is a pragmatic entrepreneur and engineer with 11 years of experience building distributed, event-driven systems and data platforms that translate into measurable business value. As co-founder and CTO across multiple ventures—most recently Lunogram and CloudProud—he blends product strategy, hands-on engineering, and AI-driven orchestration to ship scalable customer- and healthcare-focused systems. He has led and mentored engineering teams at scale (Shell, Worldline) while authoring open-source infrastructure like Semaphore v2 and driving migrations to cloud-native stacks using Go, Kubernetes, Kafka, and gRPC. Based in the Netherlands, he also cultivates the regional developer scene through DevPulse Zwolle, showing a knack for turning technical depth into community and commercial impact. An active low-level protocols enthusiast, Jeroen is equally comfortable moving bits in production as he is designing the higher-level orchestration that makes them useful.
