Wells Fargo Bank, Charlotte, NC September 2015 – December 2017 Java/J2EE Developer

XN is one of the document delivery applications in Wells Fargo. It creates, modifies, changes, transforms files over wells Fargo banking system. The goal of the group was to create a large set of reusable processes which enables XN to process different types of files in requested manner (Right now there are 912 different processes and it is progressively increasing). Usually, files are printed using large printers, which are capable of printing more than 14 million pages per month. XN is responsible for creating the letters and transforming them to/from a printer readable format (AFP, PCL) file and possibly push them through other applications. XN also provides online control over files being processed. The backend APIs were written with Java, Spring boot and Hibernate and the frontend of the application was written with Angular JS. The challenge was to create one application, which can process different files such as taxes, advertisement, customer notifications and offers or checks. The application was developed as a number of actions, which are completely independent and reusable. Each process takes a set of actions with certain configurations along with it. It is a multithread application written in JAVA, Shell script, SQL running on a Linux server in a TDD (Test Driven Development) environment. The web GUI uses a single sign on for authentication and includes customer portal and internal apps. The customer portal makes it possible for customers to track the process of their files at high volume without directly communicating with XN. The Internal portal enables XN to create processes and configurations, handle failure and production issues through the GUI. The team consists of no QA team and testing was entirely done by the developers. Ali Rahmati
