At Tata Consultancy Services, I optimize Oracle SQL and PL/SQL for the TCS BaNCS core banking platform, supporting high-volume banking transactions and reporting.
I've improved execution time by 30% across 50+ complex SQL queries and designed procedures, triggers, and materialized views for systems handling 10+ TB of transactional data.
I support international banking clients including Nedbank and SBSA, lead root cause analysis, and reduced recurring production incidents by 90% through permanent fixes and monitoring improvements.
I've built a scalable Oracle Materialized Views replication framework for real-time reporting, developed data transformation logic and optimized pipelines, and enabled custom reporting through BusinessObjects.
