Full Description
Stuck with a bug that won't go away? Getting errors you can't trace? I'll find and fix one specific bug in your React, Next.js, or Laravel application — fast, clean, and with a real explanation of what was wrong.
Whether it's a runtime error, a hydration mismatch, a broken API call, a CORS issue, an authentication bug, a database query problem, or a broken form — I diagnose the root cause (not just the symptom) and fix it properly. I don't slap a patch on top; I find why it broke and make sure it stays fixed.
What makes this different from other bug-fixing offers: I test the fix in a staging environment and send you a working preview before I call it done. You'll see the fix working with your own eyes before you accept delivery.
I've fixed hundreds of bugs across React, Next.js 15, Node.js, Express, Laravel 11, PHP, and MongoDB/PostgreSQL/MySQL databases. I've also worked with Tailwind CSS, Bootstrap, and complex CSS issues across every major browser.
This Micro Zinn is a low-risk way to see how I work. If you like the quality of the fix, most buyers come back with larger projects — because they know what to expect from me.
Send me your bug details (error message, stack trace, screenshot, or steps to reproduce) and I'll get started immediately. If you're not sure how to describe the bug, send me a Loom video or a screen recording — I'll take it from there.
Delivery in 48 hours or less for most fixes. Complex bugs may need more time, and I'll tell you upfront before accepting the order.
• The actual fix applied and tested
• A working staging preview URL to verify
• A short written summary of what was wrong and what changed
• 1 round of revisions if the fix needs adjustment
• Post-fix support for 7 days
A Next.js 15 restaurant SaaS app had a JWT authentication loop — users were logged out randomly after 5 minutes. I traced it to a token refresh timing issue, fixed the interceptor logic, and reduced auth failures to zero.
An API endpoint was taking 4.2 seconds to respond due to an N+1 query problem. I added proper eager loading and one index, bringing response time down to 150ms — a 96% improvement.
A React frontend couldn't communicate with its Node.js backend due to CORS misconfiguration and missing preflight handling. I fixed the middleware on both ends and restored full API communication.
