At YOUGotaGift, I developed and maintained five B2C and B2B platforms for YOUGotaGift.com, a digital gift card marketplace. I modernized frontend architecture and reduced technical debt by ~30%.

I built 100+ reusable components and scalable features, and improved page-load performance by ~35% through server-side rendering, lazy loading, code splitting, caching, and optimized GraphQL queries.

I strengthened testing and production monitoring, contributing to ~25% fewer production defects. I also mentored 5+ frontend engineers through code reviews and Agile knowledge sharing.

At Tegain, I developed React interfaces, integrated REST APIs, and built cross-platform React Native functionality for Android and iOS. At Talrop, I developed responsive React web interfaces and integrated REST APIs.
