A client in the transport industry needed a smartphone-based delivery system built as a complement to their existing Warehouse Management System. I was hired as a subcontractor to build it, creating the app in HTML5 / PhoneGap using jQuery Mobile and Backbone.js.
The app captures data for each delivery, including the delivery signature (HTML5 Canvas) and location tracking, via a custom PhoneGap plugin I wrote. I also built the backend DMS system, which includes a JSON API and web portal for tracking deliveries and viewing the proof of delivery, all developed in Ruby on Rails and deployed on Heroku.
Later, I was engaged to help implement the system for a number of customers, including building interfaces between DMS and the customer’s existing transport system.
