Projects

MSDP DWH to GCP migration: It is a migration and development project in which the existing data warehouse environment is migrated to Google Cloud Platform. The data from the on-prem Teradata warehouse is loaded into the GCP Data Lake store and then processed through various GCP services into Big Query, on which SAP BO is used for reporting.

Automated data purging framework for legacy source systems:- This project focused on designing and implementing a robust and automated data purging solution across multiple critical legacy source systems. The primary objective was to address the challenge of ever-growing database sizes, which were leading to performance degradation, increased storage costs, and potential compliance risks related to data retention policies I designed and implemented a centralized configuration management table to store dynamic purging parameters
