    A Web Developer using Open Source Technologies.

    Mexico - Last active: 5 hours ago - Tests: 12 - Portfolio: 15

    I only work on hourly projects. Thanks! A fast learner and problem solving oriented programmer. I am a Web Developer and loving it! Do contact me to start a discussion about your project and how I can help! Work Policy: * I never bill for learning time. If a feature/project requires me to learn something new, I won't bill you since I'm already adding value via the newly acquired knowledge. * I try to deliver the best quality possible, but this is often a trade-off between time, budget, and the specific project situation. (For example, not all clients would want the time/money investment to create a full unit test suite) * I'll be honest. For example, I like giving suggestions on how to save time/money even if that means less billed hours for me. Frameworks I've used: Zend Framework, CodeIgniter, Drupal, Wordpress, ExpressionEngine, jQuery, YUI, a bit of Symfony, Ruby On Rails, Symfony, Flask. Technologies I've used: SQL, HTML, CSS, Javascript, PHP, Ruby, BASH, mySQL, PostgreSQL, Python.

    Over the last 15 years I have continued to develop my career, skillset, knowledge and experience. The last couple of years, upwork has introducted me to a great number of great people and projects. This has been right across the board, from a medical scheduling database (written in VB), to creating and maintaining a 3 million hits /day infrastructure (PHP, MySQL), to data scrapping and manipulation (PHP, import.io). I would like to continue to be exposed to new and different challenges, that will further develop my skills and career. I also really enjoy making new contacts on the upwork network. I look forward to the many varied opportunities and roles that upwork offers.
