You will get - Debug Your Web App & Fix Your Codebase React & Next.js
Project details
You did not build something broken on purpose.
But right now something is broken and it is
costing you time, money, or both and the
developer who wrote it either cannot fix it
or is no longer available.
That is the exact situation I fix every week.
I debug React frontends, Node.js backends,
REST APIs, MongoDB queries, authentication
flows, payment integrations, and everything
in between. Not with guesswork with a
methodical process that finds the real root
cause instead of patching symptoms until
something else breaks.
The most common bugs I fix are the ones
that have already been looked at by two
or three developers who could not find
the problem. Race conditions in async code.
Memory leaks in React components. Broken
JWT flows that only fail for specific users.
I also fix the problems that nobody calls
bugs but that are quietly killing the
product disorganized GitHub history with
no branch structure, no CI/CD pipeline, no
README, and code that only the original
developer can understand.
You will get a fixed application, a clean
GitHub repository, and a written report
explaining every single change so you
are never in the dark about your own code.

About Musiabe
Full Stack AI Developer | React, Node & OpenAI | Chatbots & RAG System

Job Success
Gilgit, Pakistan - 7:26 am local time
I build full stack AI applications chatbots, RAG systems, and AI agents combining React/Next.js on the front end with Node.js and the OpenAI API on the back end. From UI to database to AI integration, I handle the entire build, so you're not coordinating multiple freelancers to ship one product.
What I build:
🔹 AI Chatbots conversational assistants that handle real user queries and plug directly into your
product or website, not generic scripted bots
🔹 RAG Systems let users search and ask questions over your own documents, data, or
knowledge base, powered by vector search and OpenAI
🔹 AI Agents & Automation multi-step workflows where AI handles decisions and repetitive tasks
with minimal manual input
🔹 AI-Powered Web Apps AI built into the product from day one (smart search, recommendations,
content generation), not bolted on after launch
TECH STACK:
React • Next.js • Node.js • OpenAI API • LangChain • Pinecone / Supabase (vector search) • REST & webhook integrations • PostgreSQL / MongoDB
Why clients work with me:
I scope every project clearly before writing a line of code, give realistic timelines, and reply fast most messages get answered within a couple of hours, not days. If something won't work well or isn't worth building, I'll tell you before you spend the budget on it, not after.
If you need an AI chatbot, a RAG-powered search tool, or AI features added to an existing product message me with what you're trying to build. I'll tell you straight whether it's a good fit and how I'd approach it.
Steps for completing your project

Delivery time starts when Musiabe receives requirements from you.
Musiabe works on your project following the steps below.
Revisions may occur after the delivery date.
Code Review & Bug Diagnosis
I read through your entire codebase, reproduce the bug in my local environment, and identify the exact root cause before touching anything so the fix is permanent not temporary.
Root Cause Report
I send you a clear written summary of exactly what is broken, why it is broken, and what the fix will be so you understand your own codebase better after this than before.
