    Programmer

    Canada - Last active: 10/13/2014 - Tests: 1

    I'm a DevOps with an interest in all platforms and languages, but specializing in Puppet and PHP. My framework of choice is Symfony2, though I'm comfortable in anything PHP and most Ruby. I manage my own cluster of servers via immutable infrastructure principles, and my home is run like a big web shop. Tons of small convenience projects give me the opportunity to work with many, many different languages and technologies. Some key words for me: PHP, MySQL, Redis, Unix, Linux, DevOps

    Expert Front End Developer - WordPress, Sass, Haml, Responsive Design

    United States - Last active: 2 months ago - Tests: 5 - Portfolio: 4

    Hi, I’m Jill Molloy, a Front End Web Developer with a background in Web Design. I’m currently living in Santa Monica, California. I am an experienced WordPress theme developer. I can create a theme from scratch, including custom functionality, custom posts and any other requirements. I can design the theme myself or I can work from provided designs or HTML/CSS sources. I am also experienced working in the Ruby on Rails framework, fully utilising the asset pipeline along with technologies such as Sass, Haml and erb. I write my CSS using Sass as a pre-processor and I compile it with Grunt.js. I am a very experienced Sass developer, working with it as long as I have been developing websites. I am very comfortable working with JavaScript and jQuery and I have some experience working with Angular.js. I also provide a consultation and code review service. If you have already hired a developer and you'd like someone to review their code and suggest improvements then I can help. If you're looking to start a new project and you're not quite sure where to being, contact me and I'll create you a complete development strategy based on your expectations and timings. I really enjoying taking on challenging projects that require me to think and push my skills further than before. I have a hard time walking away from a problem before it is solved and I enjoy working in teams of talented individuals that will provide alternate perspectives and approaches to the tasks at hand.
