My first project was a site I created from scratch using Treehouse, which helped me create a basic site with three pages. Then, I took what I had learned with CSS and HTML5 and began changing the pages and the layout to fit a blog-style site.
Since beginning work as a full-time web developer, I've primarily been doing projects for the customer-facing sites for our company. Often, I like to play around with the functionality locally or in CodePen when trying to get a new feature working. You can check out my CodePen profile here (both the Showcase and Forked tabs).
