You will get React Next.js Website Bug Fixes | Error Debugging | Full Stack Developer


Project details
Is your React or Next.js website throwing errors, crashing, or not working the way it should? I'll find the bug and fix it — fast.
I specialize in debugging React.js and Next.js apps. Whether it's a broken component, failing API call, hydration error, build failure, or a feature that stopped working — I find the root cause and fix it properly, not just patch it.
WHAT I FIX:
Console errors and warnings
Broken components or UI issues
API/fetch call failures
Next.js build and deployment errors
Hydration mismatches
State management bugs
Routing issues
Library conflicts
You'll get a short report and video walkthrough showing exactly what was wrong and what I fixed — so you're never left guessing.
I build full production apps as a MERN/Next.js developer, so fixes are permanent, not band-aids.
Send me your bug list and let's get your site running clean again.

About Muhammad
Full Stack Developer
Karachi, Pakistan - 8:57 am local time
One of my own SaaS products: 12Commerce now runs at $2k/month MRR built, launched, and maintained end to end by me.
I do not chase demos or flashy prototypes, I build systems that actually generate revenue for the businesses.
Hey, I am Muhammad Ahmed a Full Stack Developer and Mobile App Developer. I am new on Upwork but i have 3+ years of experience building and shipping real world products. I build web applications using TypeScript, Reactjs, Nextjs, and Nodejs, I build Mobile apps using React Native to ensure stability, scalability, and performance from day one and If you need a SaaS platform built, I will build it in a way thats designed to 3x your revenue, not just look good in a demo. I work with startups and founders who want more than just an MVP they want a production ready product that can handle growth, payments, and long term evolution without constant rebuilding.
I build production ready platforms including:
SaaS Development
I have built and scaled my own SaaS product, 12Commerce, from idea to $2k/month MRR handling everything from multi tenant architecture to Stripe billing integration and production deployment. When I build your SaaS, I design it to handle growth, payments, and long term evolution without needing a rebuild six months in.
Mobile App Development (iOS & Android)
Using React Native, I build mobile apps that feel native, perform smoothly, and are stable enough for real users from day one not just a prototype that breaks under load. I handle the full mobile pipeline: UI, state management, API integration, and app store deployment.
Dashboards & Admin Portals
I build internal tools and admin systems that give founders and teams real-time visibility into their operations — clean, fast, and built around your actual business logic, not generic templates.
Subscription & Billing Systems
I integrate Stripe and other billing providers to handle subscriptions, invoicing, and payment flows correctly — so you don't lose revenue to broken edge cases.
Multi-Tenant Platforms
I've built multi-tenant systems from the ground up (including 12Commerce and an LMS), handling tenant isolation, role-based access, and scalable data architecture.
Workflow Automation & AI-Powered Applications
I build systems that reduce manual work — from automated business workflows to AI-integrated features that add real functionality, not just a chatbot bolted on for show.
Client Portals & Custom Business Software
I build portals and custom internal software tailored to how your business actually operates, so your team isn't fighting the tool to get work done.
DevOps, Deployment & CI/CD
I don't just write code and hand it off — I set up proper deployment pipelines so your product ships reliably every time. This includes Dockerized environments, CI/CD pipelines (GitHub Actions), automated testing before deploy, and production hosting on Vercel or cloud servers. Your product goes live the right way, and stays stable as you push updates.
My Stack
Next.js, React.js, React Native, Node.js, TypeScript, PostgreSQL, MongoDB, Stripe, Docker, GitHub Actions, CI/CD Pipelines, Vercel, Redux Toolkit, AWS, n8n, Nginx
As a Full Stack Developer, I handle projects end-to-end — frontend, backend architecture, database design, API integrations, authentication systems, deployment, and scaling. I've worked across Islamic, e-commerce, SaaS, operations, education, fintech, and automation industries.
Clients usually hire me when they need:
A complete platform built end-to-end, not just a piece of it
A scalable web or mobile app built properly from the beginning
Someone who understands business logic and operations, not just code
A production-ready SaaS product that can handle growth and payments
Clean architecture that won't need a rebuild as they scale
Reliable deployment and CI/CD setup so updates don't break production
If you're looking for a Full Stack Developer and Mobile App Developer to build a scalable SaaS platform, mobile app, dashboard, or custom web application — feel free to message me.
From MVP to scaling thousands of users — I will help you build it right.
