While working a contract at the University of Pittsburgh I designed and built an interactive housing and dining map that could display in two different sections of the website (housing services, dining services). There are two pages, but they only reference one code base for the map.
When I finished the product, I built a maintenance page for internal use. It was built to simplify the structuring of JSON, recording marker and polygon locations, and explain some of the inner workings of the interactive map.
