What I'm looking for

I'm looking to build and optimize reliable ETL pipelines, data warehouse solutions, and large-scale data processing systems that support business-critical reporting and analytics.

At Infosys, I build and support enterprise ETL workflows, complex Oracle PL/SQL components, and data warehouse solutions for reporting, analytics, and regulatory requirements. I use Databricks and distributed processing to transform and analyze large-scale datasets while maintaining data quality, consistency, and reliability.

I've optimized SQL queries and batch jobs, implemented validation, reconciliation, and error handling, and provided production support through monitoring and root-cause analysis. I also developed Java and Spring Boot REST APIs, integrating relational databases through JPA/Hibernate and securing access with Spring Security.
