EXPERIENCE:
CRT Securitization Oct 2022 – Now
Senior Software Engineer
Freddie Mac,
McLean, VA
The Formula One team is tasked with providing a central location where various clients can request data elements and calculations. The team currently has 4 microservices stood up which provide access to several tables across various data sources and calculations derived by logical business rules and computational formulas.
Calculations
The calculation service currently has two APIs which support general calculation requests and eligibility.
data needs. A JSON file structure is defined for requests and responses for each end point.
The Calculation service is integrated with DAS and DRS, so if dependent elements are required to complete a calculation, it can source the data appropriately. The Calculation Service leverages the Wrapper Framework, which evaluates the Endpoints and File Structure and ensures all required inputs are provided to complete a requested calculation.
Data Acquisition Service
The Data Acquisition Service (DAS) provides clients with data in various tables in Sec TDS, CDW, & LCVA database. Subject Areas provide clients with a view inside a database and can be limited to a single table or a join across multiple tables. Subject Areas have their own respective required elements and parameters required for successful execution. Since the calculation and DAS services are integrated, clients can request DAS elements directly from the calc service instead of splitting calcs and data pull into separate requests.
Data Retrieval Service
The Data Retrieval Service (DRS) provides the ability to move data from one source to another.
The DRS currently only serves Loan Collateral Valuation Activity (LCVA)
data needed as it moves Loan Selling Coverage History table from its source database.
into its own DRS database
