Thats what I do; for a living, as a hobby and my profession. I have been a Web Designer in San Diego for almost 4 years, working for companies that create Web 2.0 social networking communities, to companies that provide professional Web Design and Development services, including Search Engine Optimization, Search Engine Marketing, Usability consulting and web development.
I have gained a wealth of knowledge and experience with CSS, XHTML, JavaScript, Photoshop, Adobe Illustrator, Dreamweaver, SEO/SEM, and many other things that are related to web design.
I recently used my skills and knowledge to quickly build a website for a very good friend of mine, who teaches spanish to young children. You can check out her website at www.bilingualchildrensacademy.com
