At Tata Consultancy Services, I led the end-to-end JDK 21 migration for SAP Commerce Cloud for Tata Steel Netherlands, from compatibility assessment and code remediation through regression testing and production rollout. The rollout had zero critical production issues.
I also developed OCC APIs for headless commerce, upgraded SAP Commerce Cloud from 2205 to 2211, and optimized Solr search, improving search performance by 40%. I automated UI and API testing with Selenium WebDriver, REST Assured, and Python Behave, reducing manual testing effort by 60%.
