I picked up Scala back in 2007 (after trying to build a company in Java and winding up in a rage over its limitations); I’ve been working in Scala full-time since 2012. I’ve been doing “light FP” since picking up the style from Ruby around 2002, and "pure FP" in Scala since 2018. During the day, I work at One Pass, building out a suite of health-maintenance tools using the Typelevel stack. In my spare time, I’m the CEO and Architect of Querki, a wiki/database hybrid designed to make it easier for individuals and communities to manage and collaborate on their data."
