I currently work with a company called 6crickets. They are a registration platform for summer camps and after-school classes, and also offer services to help parents find and schedule these camps and classes.
My primary role with the company is to offer technical support, but occassionally I also create some graphics and ads for their marketing ventures. Below are some of the projects I have done for them so far.
One thing to keep in mind, I was also creating these graphics while I was still providing technical support and performing other tasks required in my role.
