- Manage complex client-side state (e.g. Redux, Zustand, Context API) and integrate applications with backend RESTful or GraphQL APIs
- Profile and optimize applications for maximum loading speed, Core Web Vitals and smooth rendering on lower-powered mobile devices
- Craft exceptional web experiences that look and feel like native mobile apps
- Optimize performance for both desktop and mobile web view browsers (including iOS Safari)
- Write clean, maintainable and testable JavaScript/TypeScript
- Conduct thorough code reviews and contribute to the shared UI component library
Requirements
