At Contus Tech, IFF, I tested FMCG data outputs against requirements and mapping rules, using SQL to find missing, duplicate and inconsistent values. I also tested a GenAI chatbot’s conversation flows, prompts and responses.

At Cognizant, Cigna – Healthcare & Insurance, I validated Informatica workflows and AWS Glue outputs, then reconciled transformed data in Amazon Redshift and Databricks. I also tested an Azure Data Factory pipeline loading CSV data into Azure SQL.

At Accenture, Fiserv Banking Project, I validated ETL outputs and banking workflows, including credit-card, loan-servicing and payment functionality across web, desktop and mobile. At Wipro, I prepared test cases, scenarios and defect reports for internal exercises while upskilling in manual, API, SQL and GenAI testing.
