Champion Mortgage Company, NJ

Mortgage Business Loan Originating System Jan 2002 – Dec 2003

Role: Sr. Java Developer

Description: This project is a B2B application and provides the business solution for the mortgage business. It is an Intranet plus Internet application, which tracks and logs all the processes occurring while processing of Loan. This is a very huge application consisting of around 120 modules. Which is a Mortgage business that is from Loan Origination till Loan funding, including the Third Parties involvement in Lending Exchange. Basically, the entire application is divided in to three parts, ADMINS, LOS (Loan Originating System) and LsXchg (Lending Exchange).

I involved in totally 3 modules .The modules what I have involved are as below

Assignments

Description: This module deals with assigning the loan to various users, vendors and territories that are related to the company. Assignments will be done at various stages of the loan, depending on the loan parameters. Assignments can be done manually or automatically based on a rotation-based system. Only those users, who are assigned, can enter the loan to place several orders like appraisal, title, credit etc and change other loan related information, which takes the loan from one stage to the other.

Call Center

Description: The Objective of this module is to store the Borrowers primary Information. Registration Application allows inquiries from customers through different channels (for e.g.: Phone, Internet) to be entered and an appropriate disposition action can be taken. This Application is the major source of information to the Loan Origination System. Once the user enters all the required information then it generates a loan number for that borrower. Once Loan number Generated, all operations are carried out using this loan number. This module is again sub Categorized into Marketing Information, Loan Information, Property Information, Borrower Information, Income Details, and Contact Information.

Property

Description: The Objective of this module is to handle all the properties of primary borrower, co-borrower & other borrowers. There are mainly 3 types of properties are handled here, Subject Property, Real Estate Property & Rental Property. Subject Property is the property in which borrower is going to take loan. Real Estate Property is the other Properties of the Borrower. Rental Property is the Rental Property of the borrower. One of the advantages of this module is separate handling of Property Information and Property Financial Information and we can attach the Property to the corresponding Liability. This module is highly integrated with Borrower, Liability, Loan Workspace and Exception System.
