At Cognizant, I test data pipelines and validate full and incremental loads for projects including NewDay Cards (UK) and Sanofi US CRM Events. For NewDay Cards, I checked data accuracy using AWS Athena and Snowflake and supported the resolution of critical defects.
On Sanofi US CRM Events, I analyzed requirements, prepared test plans and cases for in-sprint and end-to-end system integration testing, and executed Informatica task flows to load data into target systems.
Previously, I worked on Novartis data quality and big data testing projects, validating data across landing, staging, enrichment, and business layers. I’ve used SQL, Hive, and Spark SQL to verify data, and test management tools to track and report defects.
