TLI is a web application system aimed at managing a purchase-delivery workflow. It handles the whole workflow, starting with the client doing the purchase and ending with the package being delivered. Its main goal is to keep continuous track of the package (where it is, in which city, truck, container, etc.) and show this information to the customer. For that reason we had to handle trip's bookings, services, drivers, carriers, shipping companies and more. The development was focused on the usability and maintainability of the system. It was developed with Ruby on Rails, jQuery, Formtastic, Cucumber and Rspec.
