    Web Designer

    United States - Last active: 4 days ago - Tests: 3 - Portfolio: 12

    Design is about presenting your message to the world. Good design does this as simply and beautifully as possible. My goal is to help you present your message in a very modern and clean way; keeping the target market in mind every step of the way. Rather than get caught in trends, I prefer to focus on and perfect the fundamentals to make your site stand out. This includes: Clean designs based on a pixel–perfect grid, beautiful typography and well thought out color schemes. I work in Photoshop and Illustrator on the Mac to craft my designs. I create Responsive WordPress websites with lean, well–thought code in Coda. SEO and content–writing are also skills I bring to the table. Please feel free to view my personal site and contact me via the contact form: http://cameroncampbell.me *NOTE: I'm fully booked until April 27th. Contact me to be placed on the waiting list. Please, no template customizations or projects with under $2000 budgets*
