At Teamware Solutions, I design and maintain Informatica PowerCenter ETL workflows, manage Snowflake data warehouse objects, and optimize SQL transformations. I also handle data migration, validation, and production support.
At Tech Mahindra, I developed Informatica mappings for SingTel data warehouse projects, tuned ETL performance, and wrote PL/SQL procedures and UNIX shell scripts. I also supported production systems and participated in Informatica platform upgrades.
On an infrastructure financial planning and analytics technology project, I migrated PL/SQL and ELT logic to Snowflake as an individual contributor, using Python and Airflow. I also served as Scrum Master for a four-member team and supported change management and deployment processes.
