I will be your senior react developer to fix bugs and build features


About this gig
Most React problems aren't React problems. They're architecture problems.
I'm a senior frontend engineer with 6+ years on production React applications, including a large enterprise ERP platform built on an NX monorepo with TypeScript, TanStack Query and AG Grid.
I work in real codebases, not toy projects. I can read an unfamiliar repo, find the actual cause, and fix it without breaking three other things.
WHAT I CAN DO
- Fix bugs in your existing React app: rendering, state, data flow, performance
- Build new features, screens and components in your codebase
- Refactor messy React into something maintainable
- TypeScript migration and type safety
- State and data fetching: TanStack Query, Redux, Context
- Complex tables and dashboards with AG Grid, forms, charts
STACK
React, TypeScript, JavaScript, Next.js, TanStack Query, Redux, Tailwind, AG Grid, NX, Vite, REST and GraphQL, Supabase, Angular.
HOW I WORK
Message me first with your repo or the problem. I'll tell you honestly whether I can solve it, how long it takes and what it costs, before you order. If it isn't a good fit, I'll say so.
You get reviewed code and a clear explanation of what changed and why.

FAQ
Can you work with my existing codebase?
Yes - that's most of what I do. Send the repo or a zip and I'll review it before you order.
What if you can't fix it?
I'll tell you before you order, not after. If I start and hit something genuinely unsolvable, I refund.
Do you work with AI-generated code from Lovable, Bolt, v0 or Cursor?
Yes. Generated React apps usually have state and structure problems. I fix and stabilise them.
Can you sign an NDA?
Yes. Happy to sign before you share any code or credentials.
