I'm Teejay VanSlyke, a freelance web engineer living in Saint Petersburg, Florida. I help entrepreneurs and agencies turn ideas into reality on the web. I take a user- and design-centric approach to my engineering practice, interested in why more than what or how.

I am currently accepting new consulting clients. Contact me for a free fifteen minute consultation..
