DivvyMaps is a Ruby on Rails application that provides optimized directions to Divvy bike riders. The application uses Divvy and Google Maps APIs to determine optimal routes to and from a Divvy station, and biking directions between two stations. The app also accounts for rides longer than 30 minutes by directing users to multiple check-in stations along their route. These calculations and visualizations were executed in Javascript. The single-page app was optimized for web and mobile using HTML and CSS.
