Microsoft Certified | Senior Developer | Team Leader

Australia - Tests: 11 - Portfolio: 3

Over the last 15 years I have continued to develop my career, skillset, knowledge and experience. The last couple of years, upwork has introduced me to a great number of great people and projects. Two of these projects will be briefly outlined below. The first was designing and implementing a 4 million hits / day infrastructure to handle advertising banners. This client had a business requirement to greatly extend the reach of the live infrastructure. This project was completed in PHP / MySQL and is currently hosted on a cloud platform. This project scales automatically as required to handle any variation in the daily load. The final project was a hospital scheduling task. This client worked for a hospital and had over 30 different scheduling rules for every time-slot. The client used to do this manually and it took hours every week. I came up with a VBA based solution that would automate this task. On completion, the task took about 20 seconds to execute and correctly assigned all time-slots to the correct hospital resources. 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.

Full Stack Web Developer

Mexico - 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.
