I'm a long-time committer of the Ruby language who wrote and has been maintaining some of the essential language features and libraries like Enumerator and Set. I'm also a core developer of some popular gems like Nokogiri, Mechanize and Feedjira, and on top of them, I've been co-authoring the web-based automation tool called Huginn. To wrap up, I've been committed to the development of the ecosystem around Ruby for making application development easier and much more fun.

I also have a long history as a FreeBSD committer to work on helping port a number of libraries and applications to *BSD platforms. You may know I'm the creator of Portupgrade.

As a long-time user of Emacs, I've written a number of elisp packages that are available on MELPA.

Once in a while, I contribute to some popular productivity tools and utilities like iTerm2, Hammerspoon, Karabiner-Elements and KeePassXC. I use them a lot, and whenever I find something I can improve, I write a patch.

I love automation and improving productivity. Get your hands free from tedious routine work. Make a computer do things for you using the power of programming. As a bonus, it is so much fun!
