About this gig

Need clean, production-ready React components or a quick bug fix? You're in the right place.


I'm a Frontend Engineer with 3+ years of experience in React, TypeScript, and scalable UI architecture. I've built and maintained component libraries, design systems, and enterprise-grade web applications.


I can help you with:

- React component development (functional, typed, tested)

- TypeScript integration and type fixes

- Bug fixing and performance improvements

- Chakra UI, TailwindCSS, or custom CSS styling

- Unit tests with Jest, Vitest, or React Testing Library


What I need from you:

- Description of the component or bug

- Repo access (GitHub/GitLab) or a CodeSandbox link

- Design reference (Figma or screenshot) if applicable
