    Web Application Developer

    United States - Last active: 2 months ago - Tests: 2 - Portfolio: 1

    Hello! I'm a web application developer experienced in HTML5, CSS3, Javascript, Backbone, jQuery, PHP 5.3/MySQL, and Java, among others. I love creating rock-solid quality code that's well commented, bug-free, and that works flawlessly on all browsers. I utilize the latest object-oriented analysis and design principals such as encapsulation, design patterns, and refactoring to make clean, reusable code. I LIVE for the feeling of just having demolished a tough programming challenge with a beautiful, elegant solution. I still make it a goal to read regularly on the latest programming technologies. I'm constantly improving, and I routinely teach myself APIs, frameworks, and even entire language depending on what the challenge calls for. I can also dig into even the most complex code bases to squash bugs or refactor. I'm friendly, cooperative, and encouraging, and I make sure I understand employer's and teammates' goals so we can do everything possible to achieve them. I can work independently and create solutions from concept to completion, or I can work with a team with specific design goals. I ask questions early and often so the product meets the design specs as closely as possible. Overall, I love the challenge and reward of programming, and would be delighted to work with you on your next project.
