Away from the desk

  • Escape Room and Puzzle Game fan. Anything that scratches the "I solved it" itch.

  • Amateur Runner. Recently hit 10km distances and have somehow got it into my head to shoot for a Half Marathon. Big step up from being peer pressured into the corporate run club.

  • Tinkering and creating artistic projects. Always on the lookout to learn something new and build something cool.
