About this gig

Stuck on a React or Next.js bug that's already eaten your day?


I'm a frontend engineer with 3+ years shipping production React and Next.js apps at funded startups. I find the actual cause, fix it properly, and explain what happened.


WHAT I FIX

- React state, re-render and hook issues useEffect loops, stale state

- Next.js hydration errors, routing, SSR/ISR and build failures

- Layout and responsiveness bugs CSS, Tailwind, flexbox, grid

- API and data-fetching errors, CORS, async race conditions

- TypeScript type errors and console warnings

- Broken deploys on Vercel and Netlify


WHAT YOU GET

- A working fix as a clean commit or a diff you can review

- A short written explanation of the root cause

- How to avoid the same bug next time


STACK

React, Next.js, TypeScript, JavaScript, Redux Toolkit, React Query, Tailwind, MUI, shadcn/ui, Node.js, Express.


Most single bugs are delivered the same day.


Message me first with the error text, a screenshot, or a repo link. I'll tell you honestly whether it's a 20-minute fix or a bigger structural problem and I'll say so if it isn't worth paying me for.
