TowRate was a startup that offered a custom service to towing companies. The site allowed subscribed companies to manage their assets, map routes, and calculate profit margins for every tow. It was built in a way that allowed the towing companies to quickly run these calculations while on the phone, so they could figure out the most profitable way to charge for each tow. On this project, I was in charge of pretty much everything except for the initial design. My job involved data modeling, loads of calculations, back-end development, front-end development, form design, and deployment. TowRate was a very javascript heavy application, using plenty of asynchronous calls for things like sorting, calculating rates on the fly, and grabbing map data from the Google Maps API. The Maps API was used to help determine mileage and time for each tow. From there, the app used extensive math and formulas to help find the best price for each call. Companies were able subscribe to TowRate on a monthly or yearly basis. I integrated PayPal's Web Payments Pro to handle these subscriptions; let users join, autorenew, enter discount codes, cancel accounts, etc. Subscribed companies could also manage their trucks (as well as truck expenses), users, tow rates, tax areas, routes, etc. It provided an all around fleet management solution to any towing company.
