I will fix bugs in your react next js or javascript web app
Bing
About this gig
Something broken and you need it working today? Send me the error and I will tell you straight away if I can fix it.
WHAT I FIX
- JavaScript / TypeScript errors and crashes
- - React and Next.js bugs: rendering, state, hooks, routing, build failures
- - Supabase database and authentication problems
- - Layout and mobile responsive issues
- - Failed deployments on Vercel
HOW IT WORKS
- Message me the error text, a screenshot, and what you expected to happen
- 2. I tell you honestly if I can fix it, and how long it will take
- 3. You order, I fix it, you get working code and a note on what was wrong
WHAT I NEED FROM YOU
- Access to the repo (a GitHub invite is easiest)
- - Steps to reproduce the bug
- - Any error message or console output
PLEASE READ BEFORE ORDERING
I work in the modern JavaScript stack: React, Next.js, TypeScript, Supabase, Vercel. If your project is WordPress, PHP, Python or something else, message me first - I would rather tell you it is not my stack than take your money and waste your time.
I ship my own products in this stack every day, so I am reading and fixing this kind of code constantly.
Message me the error before you order.

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.
