👤
Senior🎓
Top SchoolVincent Van Der Leun is a pragmatic senior Java developer with nine years of focused experience building and refactoring cloud-native back-end systems, currently working at Kamer van Koophandel after a long tenure delivering data pipelines and serverless solutions on Google Cloud. He combines deep JVM expertise (author of "Introduction to JVM Languages") with hands-on skills in databases (relational and NoSQL), SQL performance tuning, and modern front-end frameworks—favoring React when full-stack work is required. Vincent thrives on rescuing complex legacy codebases by designing minimal, safe steps to add features or fix critical bugs while preserving architecture and system stability. He regularly bridges product and support teams, translating stakeholder needs into pragmatic designs and coaching colleagues through code reviews and knowledge sessions. A lifelong learner who started coding at eight, he also brings practical tooling experience across Docker, Apache Beam/Dataflow, and cloud KMS-driven deployments.
