EXPERIENCE
Aug ’14 - Present
Java/J2EE Developer, Freddie Mac, McLean, VA
Price Definition System (PDS)
Currently Freddie mac is limited in its pricing options. This places it at a disadvantage in a growing
segment of the market, hence an effort was initiated as part of Pricing Execution to re-write the entire
pricing application from scratch. The essential goal of this effort is that Freddie mac needs to be able to
offer a cash pricing option for the full range of loans, and not be limited to fixed-rate loans. They also
require a wide range of execution options. In addition, they need to be able to make changes to pricing
component levels, pricing groups, sellers groups, eligibility groups and buy ups and buy downs in real
time.

Pricing Execution-ADS (Attribute Definition Service)
ADS (Attribute Definition Service) application governs the service to define the attributes, its metadata
and valid values for attributes of single and multi-family loans in Freddie Mac. The ADS application is
built such that it is incorporated in other applications like selling, price definition etc. It acts as a
dictionary of attributes. There are several business rules and validations that are performed on attributes in
ADS. Users from selling and price definition call the interface to invoke and access ADS services. ADS
enables the users to define set rules by accessing the ADS application. They can view all details about an
attribute and make required modifications. The user also has the ability to view and modify the metadata
and valid values for the attributes.
