    Summary

    I wrote my first BASIC program on paper in 1981, and I have worked professionally with software development since 1996, mostly creating web-based systems. I have done extensive work with Java, Ruby, and Python but would love to work with Kotlin or Clojure. In general, I favor working with open-source products and frameworks over proprietary solutions.

    As my first professional assignment was a Smalltalk project, I was early on trained in what was to be called Agile methodologies. I have run projects using XP and Scrum since 2001 and am today an active member of the agile community in Sweden as a conference arranger and speaker.
