Top SchoolGijs Leussink is a Senior Software Engineer with over a decade of experience building resilient backend systems and CI/CD platforms across domains like banking, airports, and mobility. He specializes in Java and adjacent JVM languages (Groovy, Kotlin) and frameworks such as Spring, Micronaut, Hibernate and Gradle, often pairing pragmatic design patterns with disciplined refactoring. Gijs has repeatedly improved delivery pipelines and observability—cutting release times from days to under an hour and migrating legacy platforms to containerized microservices on OpenShift.
