I will fix bugs and errors in your react, next js, node or python web app
Mahin Anowar
Acerca de este Servicio
Stuck on a bug you can't crack? Send it to me I'll find the real cause and fix it properly, not with a band-aid.
I'm a full-stack developer who fixes bugs and errors in:
- React / Next.js hydration, state, rendering, UI issues
- Node.js / Express & Python / FastAPI backend, APIs, database
- TypeScript / JavaScript, build & deployment errors
Why trust me: I've had bug fixes merged into major open-source projects React Router, ESLint, Axios, Node.js and Jest. Digging into unfamiliar codebases and finding the root cause is literally my main skill.
What you get:
- The bug fixed and fully tested
- A clear explanation of what caused it
- Clean code that matches your existing style
How it works: message me your repo/code and what's broken (screenshots or error logs help). I'll confirm the scope and timeline before you order.
Whether it's one stubborn error or several, let's get your app running. Message me first so I can check your issue and suggest the right package.

Hi, I'm Mahin — a full-stack developer from Bangladesh (CSE @ North South University).
I work with JavaScript/TypeScript (React, Next.js, Node) and Python (FastAPI), plus PostgreSQL & MongoDB. I build complete web apps from scratch — including NSU Insights, my own AI platform used by 1000+ students — and I'm especially strong at digging into unfamiliar code to find and fix the real cause of bugs.
I've had fixes merged into major open-source projects — React Router, ESLint, Axios, Node.js, Jest and more.
Need a web app built or a tricky bug fixed? Send me the details and I'll handle it.

FAQ
What do you need from me to get started?
Your code or repo access, a clear description of the bug, and steps to reproduce it. Screenshots, error messages, or console logs help me find the cause much faster.
What if you can't fix my bug?
I'll always be honest upfront. If I investigate and genuinely can't solve it, you get a full refund. But finding the root cause in unfamiliar code is my main skill — most bugs are very fixable.
Is my code safe and kept confidential?
Absolutely. Your code and data stay completely private, and I'm happy to sign an NDA if you need one.
I'm not sure which package fits my issue — what should I do?
Just message me first with the details. I'll review the bug, tell you honestly what it'll take, and recommend the right package. No surprises.
Can you also add features or build new pages, not just fix bugs?
Yes — I'm a full-stack developer (React, Next.js, Node, FastAPI). If you need new features or a full app, message me and I'll set up a custom offer.
