Rockstar🎓
Top SchoolPeter Strömberg is a Stockholm-based software developer with 17 years of experience specializing in Clojure and developer tooling. Creator and lead maintainer of Calva, he blends full-stack consulting work with deep open-source contributions—most notably enhancing clojure-lsp and building performant Clojure implementations like an optimized Sieve of Eratosthenes. Comfortable across backend, frontend, product and UX, he prefers functional, data-oriented design and structural editing refinements (Paredit) that improve developer workflow. A longtime advocate for open collaboration, he routinely upstreams fixes and features to benefit broader communities. Colleagues know him as a pragmatic engineer who pairs curiosity with a focus on developer experience, and who still finds joy in programming while balancing life as a husband and dad.
