About this gig

Stuck on a React bug or need a feature shipped fast? I'll fix it properly, with clean, typed code that fits your existing codebase.


Why me:

  • Senior Frontend Developer with 8 years of React and TypeScript in production
  • Experience on high-traffic automotive e-commerce sites and an AWS console (former Amazon contractor)
  • Code-review mindset: I explain what was wrong and why the fix works


I can help with:

  • Bugs in React, Next.js and TypeScript
  • State management issues (Redux, Context, hooks)
  • Hydration errors, build and Vercel deploy failures, slow pages
  • Forms and validation (Formik/Yup)
  • API integration (REST, GraphQL)
  • Responsive layout and accessibility (WCAG) fixes
  • Jest tests for the code I touch


How it works: share repository access and steps to reproduce. I'll work on a separate branch and open a pull request with a clear description of the changes.


Please message me before ordering so I can look at the issue and confirm the right package.
