Summary
👤
Senior🎓
Top SchoolJeroen Ketelaar is a pragmatic CTO & CISO with 12+ years of hands-on engineering and leadership experience building cloud-native, microservices platforms across .NET, Java, Go and Rust. He co-founded multiple ventures (Intercube, Parabot) and repeatedly marries developer-friendly automation with security-first operations—designing IaC, CI/CD and Vault-backed deployments that scale and withstand DDOS pressure. Comfortable shifting between low-level systems (custom load balancers, ASM-based hooking) and high-level product ownership, he mentors teams in TDD/BDD, DDD and SAFe while shipping frequent customer-driven releases. A lifelong learner who earned a Master in Software Engineering in the US, he still builds frameworks and tools to understand and improve existing ecosystems. Based in the Netherlands with international experience in Oslo and the US, he blends startup grit with enterprise discipline to deliver auditable, resilient systems.
