Frontend Development
As well as being a very experienced backend PHP developer I am also experienced with frontend development.
HTML5 / CSS3
I have excellent knowledge of HTML and CSS and stick to best practices.
SASS / LESS
SASS and LESS are preprocesser languages which are used to render CSS styles sheets. I have experience of using both but more SASS.
Javascript, Jquery and AngularJS
I have used Javascript on an almost daily basis for the last 5 years. Jquery is the Javascript framework I most commonly use although on a few more specialised projects I have used AngularJS.
