In my unending quest for knowledge I've learned to work within the Express, Django, and Ruby on Rails frameworks, managing data both with ORMs and vanilla SQL. I'm most comfortable when a REST API with JSON endpoints serves to drive an application.
Design is a passion, and I take every opportunity to learn better design skills and tools. I like to use Sass when writing CSS, but with advancements in the spec I've become more comfortable writing next-generation vanilla CSS. I use Photoshop and Illustrator or GIMP and Inkscape for graphics design.
I'm a total Linux geek. I administer my own server with nagios/icinga, automatic backups, and mdadm RAID mixed with LVM. I manage my own Jenkins CI and Selenium servers for running unit, functional, and acceptance (aka integration) tests and have used Docker, Vagrant, and Puppet for environment management.
