About me

I work as a developer at Codestar in the Netherlands. I’m a polyglot developer and have professionally written code in languages such as Delphi, Ruby, Java, and yes, even VBScript. For the past several years I have been enjoying Scala.

I’m the author of EqualsVerifier, a tool to make rigourously testing Java’s equals and hashCode methods a one-liner.

I often go to concerts, and I keep a list.
