What I'm looking for

I'm looking to build reliable, high-performance React applications in a fast-paced Agile environment, working on scalable state management, API integrations, and production-grade user experiences.

At FanToPark, I build and maintain React.js and TypeScript features for production web applications, including end-to-end Cashfree payments and TBO Hotels booking workflows. I design frontend-to-backend data flows for third-party APIs, covering validation, response mapping, loading states, retries, and error handling.

I reduced the production bundle from 15 MB to 7.5 MB through code splitting and lazy loading, and built a React Error Boundary that recovers from chunk-loading failures after deployments. I also implemented RBAC, deep linking, Redux Toolkit, and Redux Saga workflows for reliable navigation and access control.

Through SyncWrite and FormCraft Pro, I’ve built real-time collaborative editing, Google OAuth and JWT sessions, dynamic validated forms, autosave, multi-step routing, and reusable UI components using React, TypeScript, Yjs, WebSockets, TanStack Query, Zustand, and Tailwind CSS.
