Summary
👤
Senior🎓
Top SchoolHenrik Lundahl is a pragmatic system developer with 13 years of professional experience, specializing in backend systems using Clojure and Java and a comfort with Kotlin for recent backend work. He blends full-stack chops—Clojure/ClojureScript, React, and Android— with cloud-native and microservice architectures (Kubernetes, Kafka), having both architected platforms and implemented production services. Henrik is comfortable across the development lifecycle, from technical pre-sales and roadmaps to hands-on feature delivery and maintenance, and he moves quickly into new domains. He contributes to open-source Clojure tooling—most notably extending a Clojure ElasticSearch client with upserts, script updates and parent-child support—showing attention to practical, complex use cases. Based in Växjö, Sweden, he pairs a mechanical engineering master’s background with a long history of consulting and product work, often choosing tools that favor robustness and developer productivity. Colleagues rely on him for steady delivery, pragmatic architecture, and an ability to switch between backend depth and client-side polish.
