I will fix bugs in your react next js or javascript web app
Bing
About this gig
Please message me before ordering with the error, what you expected, and how to reproduce it. I will confirm the scope and suitable package first.
I fix JavaScript/TypeScript errors, React and Next.js issues, Supabase database or authentication problems, responsive layouts, and Vercel build/deployment errors.
PACKAGES
Basic: one agreed, reproducible bug.
Standard: up to 3 agreed bugs, or one bug plus an agreed small feature.
Premium: an agreed list of issues plus a short written report on what was wrong and why. Confirm the list before ordering; this is not unlimited support for an entire system.
YOU RECEIVE
The changed code, a brief note on what changed, and checks of the agreed behavior. New features or unrelated issues need a separate scope.
I use AI-assisted development and test the agreed behavior before delivery.
Please provide the relevant code, setup instructions, and reproduction steps. Share access by an appropriate collaborator invite; do not send passwords in chat.
I work through written messages. WordPress, PHP and Python are outside this Gig.

Booking, dispatch and admin dashboards for small businesses
- FromTaiwan
- Member sinceJul 2026
Languages
Chinese, English
I build the software small businesses actually run on: booking systems, dispatch tools, admin dashboards and CRMs.
I came to this from construction work in Taiwan. My first build was a dispatch tool that pushes job assignments to workers' phones in one click - I built it because I was the guy waiting for that message.
Live now: a multi-tenant salon platform running a real studio's bookings, customers, staff and revenue every day, plus a Chrome extension with 425 users.
Small fixes and new features welcome too. Message me first so we can scope it.
FAQ
What if you cannot fix it?
Message me before you order and I will look at the error first. If I take the order and genuinely cannot fix it, I will cancel it rather than waste your time.
Is WordPress, PHP or Python included?
No. I work in React, Next.js, TypeScript, Supabase and Vercel. I would rather tell you upfront than take an order I cannot do well.
Do you need access to my code?
Yes - a GitHub collaborator invite is easiest. I only touch what we agreed, and I will tell you exactly what I changed.
Can you add a small feature instead of fixing a bug?
Small ones, yes - that is the Standard package. Anything bigger, message me and I will send a custom offer with a clear scope.
Can we do a call?
I work in writing only - my English is much better written than spoken, and messages give us both a clear record. Send me the error and a screenshot and I will reply fast.
