Facility Inspection Tool (Fit) – FIT is a restful web application built to run on a desktop as well as an iPad. The front end is bootstrap and AngularJS. Back-end server was an Oracle 10g. On the iPad PouchDB was used to store data locally until an internet connection could be established to send data to the server. Utilized Angular to write custom directives and custom filters, as well as CSS transformation using conditionals. Angular was also used for Single Page Application (SPA) for Postal inspectors, and used back-end rest calls with data binding, all through Angular. As a team member, primary development areas were photo management, external vendor data processing and automated deficiency transfer to the electronic Facilities Management System (eFMS) maintenance module. Photo manager is a file up-loader/viewer that would automatically re-size images on upload and store photo comments into the EXIF data. Due to poor internet connection in rural areas, came up with a process to auto re-size on the client side before data transfer, to conserve bandwidth. Photo manager was built with a restful service on the back-end. Created and implemented Interface Control Documents (ICD) for external vendors to adhere to when transmitting files. Implemented a Spring Boot/Spring batch job multi-threaded batch processing. Batch process was executed at regular intervals using Control-M, to process incoming vendor data.
