I will fix one react or nextjs bug within 24 hours
Ghislaine K.
About this gig
Is a React or Nextjs bug blocking your website or deployment?
I will diagnose and fix a clearly defined issue in an existing React, Nextjs or TypeScript project. BlackStone Digital brings production experience across frontend development, API integration, responsive UI, performance and deployment.
I can help with:
- component rendering and state errors
- TypeScript or JavaScript errors
- broken forms, buttons or navigation
- responsive CSS and mobile layout issues
- API data fetching and integration bugs
- Nextjs routing, hydration, build or Vercel deployment errors
What you receive:
- a tested fix for the agreed scope
- clean code changes or a patch
- a written explanation of the cause and solution
- verification on the relevant desktop or mobile flow
Please contact me before ordering if the issue involves authentication, payments, databases, third-party services, production access or an unclear error. Complexity matters more than the number of messages or console errors.
This Gig covers fixes in an existing codebase. New features, redesigns, full rewrites and ongoing maintenance require a separate custom offer.

FAQ
What do you need from me to start?
Please provide steps to reproduce the issue, screenshots or a short video, error messages, the relevant code or repository branch, and a test environment when needed. Use temporary limited access rather than sharing personal passwords.
What counts as one small bug?
One small bug is a single reproducible issue with a limited scope in an existing codebase, such as a broken component, form, layout or build error. Please message me first if the cause or scope is unclear.
Can you work directly on a production website?
Yes, when the scope and access are agreed in advance. I prefer a repository branch or staging environment, with backups and a reversible deployment. Urgent production incidents or server access may require a custom offer.
Are new features or a redesign included?
No. This Gig fixes agreed issues in an existing React or Nextjs project. New features, redesigns, migrations, full rewrites, new backend systems and ongoing maintenance require a separate custom scope.
When does the delivery time begin?
The delivery period begins after the order requirements are complete and the necessary files or access are available. If the submitted issue differs materially from the agreed scope, I will propose the appropriate package or a custom offer.
