about
I'm Opes, or Dani. I build small web tools, websites and browser extensions usually because I wanted the thing and couldn't find one that worked the way I wanted it to.
Most of it ends up on GitHub or on this website. If it's a browser tool, it'll probably hit the Chrome Web Store too.
My latest work is MittensFit.com, a fitness coaching website for one of my good friends, and Patch Collector, which downloads guitar patches in bulk from Line6 CustomTone so you don't have to click manually.
