I build websites mobile-first with HTML5, SASS and have experience with a host of Javascript libraries including jQuery, React and Backbone, amongst others.
I compile and manage frontend resources using NodeJS and webpack - and test using Jasmine when necessary. More recently I have implemented bleeding edge ES6/ES7 features into my code.
I build websites on Docker with a full CI integration. I have excellent knowledge of PHP and MySQL. I manage backend dependencies using Composer.
I have worked extensively with Magento eCommerce and have experience with wordpress.
Last but not least... I use Git for everything!
