Professional Experience
Client: Mastercard Jan 2024 to Present
Role: Senior Java Developer
Description:
Data science teams are frequently searching for data assets to leverage for model creation and training. Identifying the necessary data sets can often be a long and tedious process without significant capabilities to search across available databases. Search capabilities should be available to integrate directly into data science tools so that they can be accessed programmatically, and results can be mined within the (Python or R) development environment. EDC Wrapper API helps leveraging the Metadata stored in Enterprise Data Catalog to be consumed by the external teams such as Data warehouse teams, data scientist teams, and all other teams within Mastercard.
The usage of the application is targeted to expose the data assets and metadata to the groups in Mastercard via a customized search within the Data Catalog.
The search criteria implemented and the lookup in the applications will simplify the native EDC UI search methods.
