Over deze dienst

ReactJS bugs breaking your app or blocking your launch?

I'll fix them fast and explain every change so your team understands why.


As a Senior React developer with 4+ years of production experience, I

specialize in React hooks errors, state management bugs, and component

issues that standard debugging tools miss. I fix ReactJS problems properly

not with workarounds that create new ones next week.


What I Fix:

  • Hooks & State Issues

- useState and useEffect infinite loops

- useCallback, useMemo, useRef misuse

- Stale closures and dependency array bugs

- Context API and prop drilling problems


  • Component & Rendering Issues

- Components not rendering or re-rendering unexpectedly

- Key prop warnings and list rendering bugs

- Conditional rendering logic errors

- React.memo and performance-related re-renders


  • State Management Issues

- Redux Toolkit and Redux Saga bugs

- Zustand and Jotai state sync problems

- React Query / TanStack Query caching issues

- Form state bugs (React Hook Form, Formik)


  • Styling & UI Issues

- CSS Modules, styled-components

- Tailwind CSS class conflicts in React

- Responsive layout breaks and overflow errors
