I've tested Crismac ENPA for Yes Bank, validating Hadoop-to-SSIS-to-SQL Server data flows, SSRS reports, and releases across SIT, UAT, and production. I also maintained 12 test servers, resolved production issues, and delivered client demos for new modules.
Previously, I tested telecom billing, prepaid, usage, and customer ETL pipelines at Newgen Technomate, verifying source-to-target mapping, reconciliation, surrogate keys, delta loads, and high-volume runs. I work across SQL, SSIS, Azure Data Factory, Azure Databricks, Postman, JIRA, and HP ALM in Agile delivery environments.
