ABOUT ME

Senior Software Engineer with 5+ years of experience

Programming is the one thing I think I could do for free. When you combine cool technologies, cooler gadgets, processing power, plenty of RAM, a clear plan, internet access, and headphones, it's a party for me! I love taking code to production and the 'god' feeling I get when I see someone served by my innovation. I seek out ways to be exposed to evolving global best practices, whet my appetite for information, and work with smart people who understand my desire to use technology to affect change for millions of people around the world.
