Summary

Senior🎓
Top SchoolDavid Humphreys is a Senior Software Engineer with 16 years of experience, currently shaping backend systems at METRO AG from his base in Connacht, Ireland. A seasoned Clojure specialist who shipped production services at Griffin, JUXT and Credit Suisse, he has repeatedly turned monolithic Java/Kotlin stacks into Dockerized Clojure/ClojureScript microservices. His background spans finance and commerce—Murex trade migrations, Datomic-backed fashion platforms, and pragmatic backend engineering—bringing domain fluency as well as hands-on implementation. An active open-source contributor, he extended Incanter with LaTeX-rendered math and richer charting features, showing attention to developer-facing tooling and data visualization. Practical, curious and migrating-proof, he’s looking for the next adventure where functional design and reliable delivery matter.
