    Portfolio & contact (returning soon - under maintenance) at: www.michaelriveraco.com I'm not passionate about programming. I'm passionate about power and beauty. That I use programming to pursue these things is incidental. I'm not a rock star, ninja, or wizard. I'm a man and I'm diligent. I'm the author of the Cali Army Knife RubyGem at www.rubygems.org/gems/cknife, a set of command line tools including an AWS S3 command line interface and an SMTP command line mailer. My blog gets 120 hits a month. Sample Google search rankings: - "admitting unhappiness" (#1) - "red black trees python" (#3) - "ruby search tree balanced" (#6) - "scheme lisp sicp" (#11) Computer specs: 32GB RAM / 500GB SSD / dual 23 inch monitors. I have a Computer Science degree. I work hourly. I don't give estimates or set deadlines. Leaving me a voicemail by phone is the best way to get my attention (as soon as I put my contact info back).  less

    I am a freelance front end developer currently based in Norwich, Ontario, Canada. Designing and developing websites has been my passion since 2003 when I helped with developing the original website for my parents car dealership. Since then I have learned many new design and development skills. I am currently employed as a sub-contractor for Sabre Hospitality Solutions but am always looking for new projects or opportunities to flex my front end development muscle. If you have an idea or project in mind, don't hesitate to get in touch and we can create something awesome! When I’m not developing you can usually find me at a motocross track, hockey arena or in the gym.  less
