    Before I even go to university i started working with Web-development. My first experience was about 6 years ago with pure HTML using frames in Dreamweaver 3. Since then I have worked hard to improve my skills in every way possible, not just as a web-developer but as a general programmer, and now I work essentially with Open Source software like Python(+Django), PHP, Linux/FreeBSD, PostgreSQL, etc.My degree in computer science helped me to understand the basics of a computer from the bits in the processor instructions to multimedia, and thus can be used everywhere to improve the final result of a project.
