Arezoo Hassannezhad

Designed and implemented a modular front-end architecture using Next.js (App Router) and TypeScript for financial data-driven platforms. Built data-intensive dashboards with dynamic tables and applied SSR, code splitting, and lazy loading to improve initial load time by ~25%. Refactored legacy React codebases to modern standards and collaborated closely with backend engineers on API contracts, loading states, and edge-case handling.

Led front-end development of a Progressive Web App (PWA) for energy management with offline support, implementing scalable REST-based data fetching for real-time metrics. Built a complex admin panel using Ant Design with charts, filters, pagination, and role-based UI behavior, and developed data-visualization components for energy consumption and device-level analytics. Performance and PWA optimizations improved mobile user retention by ~30%. Selected project: https://parla-web.vercel.app/en

Built and maintained production web applications using Vue.js, Nuxt.js, and modern frontend practices, focusing on reusable components, responsive layouts, and REST API integration. Collaborated closely with designers and backend developers to deliver features end-to-end while improving performance and maintainability of existing applications.
