I will fix your javascript, react and node js bugs fast


About this gig
Broken JavaScript? I'll find the bug and fix it usually within 24 hours.
I'm a full-stack engineer with 11+ years building production apps and APIs for European startups. I've debugged everything from silent React re-render loops to Node memory leaks and async race conditions that only appear in production.
What I fix:
- React / Next.js state bugs, hooks, re-renders, hydration errors
- Node.js / Express / NestJS async issues, API errors, crashes, memory leaks
- Vanilla JS, jQuery, AJAX legacy code that suddenly stopped working
- Build and deployment failures (Webpack, Vite, npm)
What you get:
- The actual fix, not a workaround
- A short written explanation of what was wrong and why
- Clean, commented source code you own
What I need from you:
- The error message or a description of the wrong behaviour
- Steps to reproduce it
- Repo access or the relevant files
Not sure which package fits? Send me the error and I'll tell you honestly no charge for a scoping answer.
Based in Pakistan (UTC+5) with strong overlap with EU hours.

FAQ
What if you can't fix the bug?
Then you don't pay. If I take the order and can't solve it, I cancel and you get a full refund. You'll still receive everything I found, the likely cause, what I ruled out, and where to look next. You're never left with nothing.
Can you fix bugs in a codebase you didn't write?
Yes, that's most of my work. I've spent 11+ years inheriting other people's code. Send repo access, the error, and steps to reproduce it, and I'll trace the root cause myself. You don't need to explain the whole project to me.
Which package should I choose?
One clear error in one file → Basic. Something intermittent, or you don't know where it's coming from → Standard. A bug caused by a deeper design problem you want fixed properly, with tests → Premium. Unsure? Send me the error and I'll tell you.
What if the bug turns out to be bigger than it looked?
I'll tell you before I start, not halfway through. Send the error first and I'll scope it honestly. if it needs a higher package, I'll say so up front. I don't begin work and then ask for more money.
Is my code safe? Will you sign an NDA?
Yes to the NDA, send it over and I'll sign before you share anything. I don't reuse or publish client code, and I delete local copies once the order is complete. Any access you grant can be revoked the moment we're done.
What do you need from me to start?
Three things: the error message or a description of what's going wrong, steps to reproduce it, and access to the code (repo invite or a zip). If it only breaks in production and not locally, mention that it changes how I approach it.
Do you work with TypeScript?
Yes. TypeScript, JavaScript, React, Next.js, Node, Express and NestJS. Same price, TypeScript usually makes debugging faster, not slower.
How fast can you start? Do you work weekends?
I'm in Pakistan (UTC+5), so I overlap with European mornings and can usually start within a few hours. Weekends included for urgent work. Message me your deadline and I'll tell you honestly whether I can hit it.
Do you offer support after delivery?
Every package includes revisions if the fix doesn't hold. Premium adds 7 days of follow-up support on anything related to that bug. If something new and unrelated comes up later, message me and I'll send a small custom offer.
