I'm trying to revive the fun and personal on the web. Part of that has been starting blogging on my on my website (this blog!). That lead to me starting Tanzawa, the custom CMS that power this site.

My current focus on Tanzawa is:
  • Refactoring the code base to make less dependent on Django forms.
  • Making it easier to deploy.

And since one side project isn't enough, I also started an app that monitors my solar array output on my roof called Sunbottle. You can see it live at

You can find me on and twitter @jamesvandyne. Oh, and on flickr, but I don't really post there.

Living in Japan

I'm living in Yokohama, Japan with my wife, son and dog. It's great. You should visit (once that's a thing we can do again).


I'm working at Kraken Technologies, part of Octopus Energy, helping to de-carbonize the Japanese electric grid. It's fun and nice to be part of a larger team working together to help prepare the electric grid for our renewable future. We're hiring!

2022 Goals

  • 100 runs -> 63% complete
  • Tanzawa
    • Strava plugin
    • Theme support βœ…
    • One-click-ish deployments -> I'm less convinced this needs to happen.
  • Visit America -> Have you seen the exchange rates? Not happening this year.
