IndiaWhat I'm looking for
At IBM India, I manage staging environments and build ETL workflows that ingest, transform, and load high-volume data from XML, text, CSV, and SQL sources. I focus on data integrity, validation, monitoring, recovery, and performance optimization for downstream warehousing and reporting.
On ESIS ECOS staging, I've enhanced SQL execution, built an SSIS retriggering pipeline for stuck transactions, implemented schema changes across Informatica, SQL, SSIS, and views, and supported SQL Server migration. I have also supported Chubb's Secure Transport infrastructure, helping users transfer files across internal and external endpoints.
