• TypeScript and React, including functional components, hooks, context, and custom hooks.
• Webpack bundling and code splitting, with component styling using SCSS/CSS Modules and Styled Components.
• Experience building and maintaining micro-frontends using Webpack Module Federation or similar platform-integrated remote module architectures.
• Strong working knowledge of GraphQL queries and mutations, Apollo Client caching and reactive variables, and type-safe hooks generated with GraphQL Code Generator or similar tooling.
• Solid React Router experience for client-side navigation, plus experience building and validating complex forms.
• Production engineering experience with frontend telemetry, error logging, feature flags, gradual rollouts, and debugging user-facing production issues.
• Experience building accessible and internationalized interfaces using shared design systems, reusable component libraries, and localization workflows.
