I have in depth knowledge of HTML5, CSS3, JavaScript, JQuery, Responsive Web Design, Sass, and Wordpress. I've also worked with lots of frameworks such as Bootstrap 3, Foundation 5, Skeleton and various other Grid systems.
I regard performance as equally important as design and I enjoy creating modular and semantic code to ensure optimum user experience.
Other notable skills and software I use include Git, GitHub, Markdown, HTML5 Boilerplate, Jekyll, Haml, OOCSS, Linux, and Web Standards.
