Charles Campbell

WEB SOFTWARE & APPLICATION DEVELOPER

Results driven freelance software and web applications developer with over 10 years of experience building scalable web applications in a variety of languages and platforms.

It all started back when I was a student at UNC Chapel Hill, and I was developing websites, teaching myself Perl in my off campus housing apartment located in Carrboro, NC. Sitting inside of apartment CC5, in between studying for my Computer Science classes, I was busy learning how the internet worked while helping others on campus with their websites.

Since those humble days in undergrad I have acquired over 10 years of software development and engineering experience in a variety of development environments and platforms. I have a wealth of knowledge in web application development, software as a service application development and the entire software development lifecycle.
