Subhanshu Sj _ Jha

Architected a multi-tenant web platform UI in React/Next.js with dynamic theming, role-based component rendering, and runtime configuration switching — enabling a single codebase to serve multiple enterprise clients with isolated data and UI contexts. Delivered a 40% LCP improvement through strategic code splitting, React.memo/useMemo optimization, asset compression, and API payload reduction — measured against Core Web Vitals benchmarks. Implemented secure authentication flows (JWT, RBAC) with frontend session management, automatic token refresh, and per-role UI access gating.
