Arne is a Belgian software developer and technical leader, public speaker, author, and digital creative.
I founded and run the Gaiwan consultancy.
I created a large number of popular libraries, in particular for Clojure, under the lambdaisland monniker, including the de facto test runner for Clojure, Kaocha.
In the past I created a number of condensed tutorial videos for the Clojure ecosystem, these are now free to watch at LambdaIsland.com.
You can find other videos of mine on the Lambda Island Youtube channel, or on the Makertube Peertube instance.
You can find some of my technical writing on the Lambda Island blog, the Gaiwan blog, and Gaiwan’s wiki-slash-pattern-repository Tea Garden.
You can find me on federated social media as @plexus@toot.cat.
You can find what I’m reading on the Bookrastinating Bookwyrm instance.
I occasionally post pictures on PixelFed.
I am one of the main organizers of the Heart of Clojure conference, which took place in 2019 and 2024.
I help maintain the Overtone live music coding environment for Clojure.
