At Rakuten, I modernized a legacy page into a dynamic React experience with BFF services and integrated UI/UX components, increasing user engagement by 30%. I also implemented real-time bookmarking for the Search Engine Results Page using React, BFF, and microservices.

I worked with backend engineers to resolve API data inconsistencies and caching issues, and contributed server-side code where needed. I also renewed a React coupon widget and added Husky pre-hook validation, increasing developer velocity by 20% and reducing CI build errors.

Before Rakuten, I developed full-stack features at NSP and Erxes, including a reusable Material UI design system and messenger features. At MKIT, I maintained an educational video content management app and developed CMS builder and car rental platform features.
