    Developer

    Australia - Last active: 02/10/2014 - Tests: 1

    I'm a software developer based in Melbourne, Australia. I'm currently working for a San Francisco-based tech company, but looking for freelance jobs to work on in my personal time. I have extensive experience with software and website development, including tools such as PHP, Ruby (and Rails), Python, MySQL, PostgreSQL, MongoDB, Redis, HTML5, CSS3, JavaScript; CSS frameworks such as Sass, Compass, Bootstrap, and Zurb Foundation; and JavaScript libraries such as Prototype, jQuery, Backbone, and Angular. I've helped develop many e-commerce sites using Magento, and I've successfully completed the Magento Developer Plus Certification exam. I'm also experienced in debugging and troubleshooting complex technical issues with these types of technologies. Improving performance for existing websites and applications is another area I've had extensive experience with, using profiling tools to understand and relieve performance bottlenecks. Lately I've been improving my skills around testability, and ensuring that code I write is covered with automated tests. I've found this provides a lot of help when designing an application, but also provides reassurance when refactoring code to meet future additional requirements. I attended RMIT University in Melbourne, where I completed my Bachelor of Science (Computer Science) and Bachelor of Engineering (Computer and Network Engineering). I'm passionate about tech, and I am always learning about new technologies and tools to get the job done more efficiently.

    Full Stack Developer with Awesome JavaScript Skills

    United States - Last active: 10/22/2014 - Tests: 2 - Portfolio: 1

    Hey, you've come to the right guy ;) Rather than tell you how qualified I am to do your job, I'm going to tell you how easy and stress-free it will be to work with me (cuz trust me, I got the code part handled) First things first, I'm doing this more for love of code than for money. I'm currently happily employed full-time by an awesome tech company here in San Francisco ;) So for that reason, I'm only taking on a project that is something I enjoy working on. Sorry folks! My pixel pushing web dev/design days are over ;) I only build full-stack web applications, with designs provided. I used to do the design as well, but that's not where I shine, the code is where I do my best work, so that's what I'm going to write for you. So, if you have a web application that you need built, and have someone else who can do the design for you, I'm happy to build it for you. Come to me with your app idea, and mockups, and I will breathe life into it. Get in touch, and we can start tackling the game plan right away! Cheers, -Andrew Languages and Frameworks I know best: -Ruby on Rails -JavaScript -Backbone.js -Marionette.js -jQuery -HTML5 -CSS3 -SASS Languages and Frameworks I'm learning: -Node.js -WebGL -Angular.js
