I like challenges, have solid skills of problem solving, do not require supervision to successfully perform my duties.

    Web Application Developer

    United States - Last active: 1 month 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.

    Senior Ruby On Rails developer

    Poland - Last active: 7 days ago - Tests: 4 - Portfolio: 6

    Software development is not only my profession but also my greatest passion and hobby. This is why I spend majority of my free time improving my programming skills, learning new concepts, technologies, languages and tools. I get the greatest satisfaction when products I develop are released to the world and people start using it - that makes me want to spend more time at work. When not in front of my monitor, I'm probably taking care of my daughter or doing some sports (tennis and swimming most of the time).
