I will fix javascript, react, nodejs and nextjs bugs
Alexandr S
About this gig
I fix bugs in web apps and sites: broken forms and buttons, broken login, layout that fell apart, console errors, a project that stopped building after an update. Stack: JavaScript, TypeScript, Node.js on the server, React and Next.js on the front end, plus plain HTML/CSS/JS, PHP, and WordPress. Not Shopify. I also work with code that was written in a hurry or generated with AI tools.
Basic fixes one reproducible problem and tells you the cause. Standard takes up to 3 and adds a written summary of what was wrong and what changed. Premium goes to 5, keeps the summary, and lists the other problems I noticed while I was inside the project. If a problem doesn't reproduce from your steps, or the fix turns out bigger than the package, I say so before starting rather than run over.
What I need from you: repository access or a project archive, and the steps to reproduce the problem (what you click, what you expect, what happens instead). A staging URL helps; for a live-site fix, add deploy access too.
Everything runs in writing. On multi-day work you get a written update at the end of each day, and I answer fast. No calls.

I fix web apps and backends that are slow, broken, or hard to maintain. I build new ones too. Web dev since 2016: JavaScript, TypeScript, React, Node.js. Rust has been my main language since 2024: APIs, backend services, CLI tools. One result I can name: a legacy PHP backend rewritten in Node.js, same public API, median response time about three times faster. Scrapers and parsers too, the kind that survive rate limits and JS-rendered pages. I work async, in writing: a short update each working day, fast replies, no calls. Past client work is under NDA, so I describe outcomes, not names.

FAQ
What if the bug can't be reproduced?
I check reproducibility from your steps before I start any work, and tell you the same day. If it can't be reproduced, we agree what to do next before anything is billed against the order, and I never run out the clock on a fix I can't make.
Is the source code delivered?
Yes: a pull request, a patch, or the fix applied to your live site, your choice.
Do you sign an NDA?
Yes, if you send one before the order starts.
Which stacks do you work with?
JavaScript, TypeScript, Node.js, React, Next.js, plain HTML/CSS/JS, PHP, and WordPress. Not Shopify.
Do you take calls?
No. Order chat only, in writing. I reply fast.
Will you work inside my repository?
Yes, with repository access or a project archive.
What counts as a revision vs. a new request?
A revision changes the fix already delivered. A different bug is a separate item: add the extra, or start a new order.
Can I get it faster?
Yes. Add Extra-fast delivery: the time halves and the price of the package doubles. Other extras keep their own days and prices. For anything faster than that, or a scope between two packages, message me for a custom offer.
