About this gig

Need a React bug fixed fast? You're in the right place.

I'm Sarah, a senior frontend engineer with 6 years of production React and TypeScript experience, most recently at iHeartMedia. I fix the bugs that have been driving your team in circles.


What I'll do:

  • Diagnose the root cause (not just patch the symptom)
  • Fix it in your codebase, following your conventions
  • Document what was wrong and how I fixed it
  • Stay available for follow-up questions


My stack: React, TypeScript, Next.js, Vite, Tailwind, REST and GraphQL APIs, Supabase, and modern frontend tooling.


Common bugs I fix: state management, rendering and re-render issues, routing, data fetching, TypeScript errors, styling, forms, and authentication.


Scope note: A "bug" is a single, isolated issue I can reproduce. New features and major refactors are quoted separately.


Message me before ordering so I can confirm I can solve your specific bug and recommend the right package. I respond within a few hours during US business hours.
