Always be building.
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.
