Summary
🤩
RockstarMichiel Borkent is a seasoned Clojure-focused software engineer with 14 years of experience, based in Amersfoort, Netherlands. He is the author and maintainer of key tooling like clj-kondo, babashka and SCI, and contributes deeply to both compiler and runtime projects such as ClojureScript and Babashka. Michiel blends backend systems work with full-stack and DevOps responsibilities—improving build and release pipelines, automating asset deployment, and adding UI tests for projects like Nextjournal’s Clerk. His contributions span high-profile open-source projects (CloureScript, Metabase, clojure-lsp) and often target developer experience, linting, and reliable tooling rather than just features. Colleagues can expect pragmatic engineering, a focus on maintainability, and an unusual knack for making Clojure tooling fast and script-friendly.
