At Extramarks Education India, I build educator-facing React applications for Assessment, Live Class, Authoring, and Question Bank experiences used by 15,000+ schools globally.
I've reduced frontend API calls by about 33% through a Node.js and Express BFF, and improved high-traffic API response times by about 37% with Redis-backed caching. I also optimize SPA performance through Vite, route-based code splitting, lazy loading, Redux Toolkit, and TanStack Query.
I create reliable learning workflows spanning STEM authoring, real-time Firestore updates, HLS streaming, offline persistence with Dexie, JWT authentication, and reusable UI systems.
