Problems We Solve

  • Your React SPA is slow — poor bundle size, no lazy loading, failing Core Web Vitals.
  • A previous London developer left you with an unmaintainable React codebase.
  • Your Angular or Vue app needs migrating to React for London team familiarity.
  • API integration is broken — your React frontend cannot reliably connect to the backend.
  • No London React developer available who understands both frontend and backend.
