Teaching since:

Not sure you have the brain or the background to be a world-class developer? Sick of your current job and dying to try something creative, challenging, and rewarding, all in an industry that's growing? I know exactly how you feel, because I was there too and I have seen and helped dozens of people break into software development with confidence and a clearer understanding of the skills involved.

I specialize in Ruby on Rails, which is a web framework that incorporates the Ruby programming language, HTML, CSS, Javascript, and database technologies--all of which you can learn quickly and master. I have been a professional Rails developer for over three years and a web developer for seven years. My background in teaching English abroad, as well as software support and mentoring developers makes it easy for me to adapt to your level of knowledge, your pace of learning, and most importantly, your STYLE of learning.

I came from a non-technical background and thought for sure that I was too "right-brained" to do this work, so I know that the struggle is real. More than anything else, I want you to know that If you are interested in programming and you are willing to work hard to understand the tools involved, then you already have what it takes. Let's get started!
