At Cognizant, I developed and optimized SQL queries for data extraction, transformation, validation, and reporting on the Apple Global Deployment project. I also worked with Snowflake to query and manage datasets for business reporting and operational support.
On the same project, I participated in ETL workflows and processed structured and semi-structured data, including CSV and JSON files. I used Python and Pandas to automate data cleansing, transformation, and validation, and supported production issue troubleshooting.
Earlier at Cognizant, I worked on the FM Global Insurance project, developing SQL queries, stored procedures, and database scripts for data processing and reporting. I also automated validation and reporting tasks with Python and participated in testing, defect fixing, deployment support, and production issue resolution.
