I suffer techno-joy, and always try to keep up with what's going on in the world of technology. I started out writing Ruby with Rails, and I have now written projects in Python, NodeJS, Ruby with both Rails and Sinatra, some evil bash scripting, and messed around with Golang, PERL, and a few others I've forgotten. I still prefer Ruby above all, but I recognize the rise of the JS train and I'm staying sharp on that end with frameworks like React.
I am definitely not a designer. CSS is yucky and while I understand it, I just don't have any talent for design. I can implement a spec - but don't ask me to look at a color wheel.
