At Alstonia Consulting LLP, I support India Post Payments Bank’s banking Data Warehouse by monitoring daily ETL and batch jobs, tracing failures to their root causes, and validating recovery. I also reconcile source-to-target data to catch missing, duplicate, or incorrect records.
I optimized complex Oracle queries to cut execution time by 25% and resolve client tickets, SQL errors, and production issues within agreed SLAs. I’ve also conducted DR drills for the SAS application.
