Balaji Balu

I’m a Data Modeler and Oracle PL/SQL Developer with 3 years of experience delivering enterprise data solutions and backend database systems for BFSI Capital Markets clients at Tata Consultancy Services. I build conceptual, logical, and physical data models, and I turn them into production-ready Oracle database implementations.

I’ve delivered complete data model and database solutions covering data model design, PL/SQL development, performance tuning, data quality validation, and production support—building 150+ Oracle PL/SQL stored procedures and improving database performance by 35–40%. I also maintain metadata, naming conventions, and standards, and provide L1/L2 support to maintain 99.9% system availability with less than 15-minute SLA response.

I’m expanding into AWS Cloud and currently pursuing AWS Certified Data Engineer Associate (DEA-C01), actively using AWS RDS, S3, and OpenSearch in production. I take pride in “zero-defect” outcomes—such as designing S2T mappings and validation for migrations across multiple banking clients with full reconciliation and business sign-off—and I bring a strong delivery mindset shaped by client collaboration and Agile execution.
