Project: Digital Document Management & Automation Platform

• Diagnosed performance bottlenecks caused by React Context API state propagation
• Helped with the planning and migration of the global state management to an architecture that uses Zustand, reducing re-render time of critical components from ~3000 ms to under 1000 ms (≈80% improvement), improving application responsiveness and general user experience
• Suggested GraphQL Codegen and later implemented it for type-safe API communication, ensuring automatic TypeScript synchronization with backend schemas and eliminating type errors from manual typing
• Migrated the platform from Create React App to Vite, significantly improving development build speeds and HMR (hot module replacement performance)
• Established comprehensive testing infrastructure with Vitest and React Testing Library, integrating MSW for reliable API mocking and integration testing
• Migrated ~50+ components through MUI v4 → v5 → v6, implementing modern design patterns with TypeScript for enhanced type safety
