At Oracle Cloud Infrastructure, I owned the migration of the IP Management Plugin from a legacy ReactJS UI to Oracle’s config-driven UI framework. I delivered 40+ end-to-end automation tests and authored the plugin’s VPAT.

At CaratLane - A Tata Product, I revamped the Exchange & Return process with a cross-platform React UI for five business flows, reducing related customer service communication by 70%. I’ve also built frontend experiences at Tata Consultancy Services and a timetable management system at Troogue.
