I am a software craftsman (senior) skilled with Ruby on Rails. I believe in elevating the professional standards of my profession to improve the end user's experience as well as my own.

I was a programmer before I ever realized it. My first experience with code was when I used Lego mindstorm's visual code builder to make my robots do cool things. I laters wrote some code to make simple video games using RPG Toolkit, as well. It wasn't until I was in college pursuing an English degree, while married with a kid on the way that I seriously considered software development as a career. I changed my major to computer science and never looked back. Now as a seasoned professional Ruby on Rails engineer with over 6 years of experience, I have been through a variety of formative experiences that have shaped me. I have taken up the cause of software craftsmanship and want to do whatever I can to raise the bar for my profession. I have seen too many unworkable code bases in my career, and I know that we can make better experiences for both end users and software developers if we persuade the world to give more respect to the software development process. I am skilled at developing well thought out software that is maintainable in the long term. I build things that last, and know how to find the bugs before they impact customers because I write robust and complete tests. I am a realist that knows how to sink my teeth into a problem and ask the right questions, whether you like those questions or not, because I know that is ultimately what is best for the business.
