What I'm looking for

I'm looking for challenging assignments where I can build, support, and improve ETL and data archival solutions while learning new technologies and delivering requirements on time.

I've supported data integration and batch operations for Cognizant clients including KBC Bank, COUNTRY Financial, Westpac, CVS, Horizon BCBS, and Merck. I schedule, monitor, troubleshoot, and recover ETL jobs using Informatica PowerCenter, Control-M, Zena, and UAC.

Across Deutsche Bank DB Feeds, I developed Informatica mappings and reusable mapplets, automated workflows, tuned performance, and supported QA, UAT, and production releases. I also build data archival solutions with Solix CDP, perform data and table analysis, validate archived data, and work closely with onshore, QA, and offshore teams to resolve defects.
