Message

At Oracle India, I engineer Oracle Retail Pricing Management capabilities hosted on OCI, supporting pricing, promotions, and clearance workflows for enterprise retailers. I also handle production escalations and product support for live SaaS tenants.

I re-architected RPM pricing cache and integration batch jobs, moving JSON payload processing to Oracle PL/SQL and implementing multithreading in Java. I also developed Oracle Retail Standard Allocation as REST APIs using Spring Boot and PL/SQL.

Earlier, at Tesco HSC, I developed retail applications and multithreaded batch processing for workloads across store locations. My work spans Oracle Retail platforms, Java, and enterprise integration, supported by Oracle Cloud Infrastructure AI Foundations and Oracle AI Vector Search certifications.
