I've divided my portfolio into three categories to represent the different aspects of my work.
Most of my professional experience has gone toward the development of tools used internally by the companies for which I work. Unfortunately, screenshots of these tools are either uninformative (in the case of command-line tools) or unavailable (due to confidentiality). I include them regardless because they do represent a different aspect to the work that is available publicly.
That's just a fancy way of describing the sites that run on my custom-built API, which I've codenamed Vigilante. I've documented the API, although by now that documentation needs serious update. A number of these sites are personal in nature, but they do demonstrate the breadth of my work, a good portion of which is self-taught.
Exactly as the title implies -- these sites were built as favors to friends (well, two in particular.) These sites demonstrate my limited abilities as a front-end designer. I don't come from a graphic design background, so my designs tend to be Spartan. But they suite their purpose well.
