Summary
👤
Senior🎓
Top SchoolHielke De Vries is a senior software engineer and security specialist based in Amsterdam with 11 years of experience building cloud-native, event-driven systems and integrating legacy HR and payments platforms. He combines hands-on engineering—Scala/ZIO, Kotlin/Spring, Kafka, Kubernetes—with architecture and technical leadership, having led greenfield projects and simplified complex systems to halve codebases and boost productivity. Hielke also runs a software and security consultancy, bringing practical offensive and defensive security skills from earlier roles in application testing and incident-driven fixes. Comfortable across the stack and fluent in automation and ML/graph-based tooling from his time at ING, he’s equally at home designing hexagonal architectures or shipping production services on Azure. A pragmatic engineer, he favors simplicity and measurable outcomes over cleverness for its own sake.
