You will get expert Bug Fixes and Feature Development for your MERN Stack App
Project details
Stop Losing Time and Users to Broken Code
A bug crashing your app or a feature stuck half built costs you time, money, and user trust the longer it sits. I fix bugs and build features in existing MERN Stack apps, jumping into your React.js, Node.js, Express.js, and MongoDB codebase to get things working fast.
What You Get
Bug diagnosis and fixes across frontend and backend
New features built cleanly into your existing code
MongoDB or PostgreSQL debugging and query fixes
REST API or GraphQL troubleshooting
Performance fixes for slow pages, memory leaks, inefficient queries
Testing before delivery so it actually works
Why It Matters
Every hour a bug stays live is an hour your users hit it too. Fast fixes and clean builds mean less downtime, fewer complaints, and a product that keeps moving.
Also Available
Urgent fixes with fast turnaround
New features: dashboards, payments, real time updates
Refactoring alongside fixes for long term stability
JWT auth and security fixes
Stripe, CRM, and third party API integration
Ongoing maintenance support
Send me the bug or feature you need, with repo access if possible, and I'll tell you exactly what it'll take.

About Muhammad
MERN Stack | Full Stack Developer | React, Node.js, Next.js
Rawalpindi, Pakistan - 6:37 pm local time
Spreadsheets that don't talk to each other. Dispatchers stuck on the phone all day. Dashboards nobody trusts because the data's always a day late. If any of that sounds familiar, that's the exact kind of mess I get called in to clean up.
What I build:
ERP & Admin Dashboards for internal operations
SaaS Platforms & CRM Systems
Marketplace & Booking Applications
Custom API & Business Automation Systems
Got a slow dashboard or a manual process eating your team's time? Message me, I'll tell you what's fixable in one message.
I specialize in operations-heavy platforms: ERP systems, logistics scheduling, and internal business dashboards, where a slow or fragmented system directly costs hours and money every week. Stack: React.js, Next.js, Node.js, Express.js, MongoDB, TypeScript, backed by REST API, GraphQL, JWT Authentication, Docker, AWS, PostgreSQL, Stripe API for anything that needs to scale securely.
DaftarPro, All-in-One Business Management & ERP Platform
Centralized ERP replacing scattered spreadsheets and manual tracking for SME operations. HR, project management, attendance, and approvals in one role-based dashboard with real-time analytics.
Result: 65% reduction in manual admin time, 15,000+ active users on this SaaS Platform.
Truck Now, Real-Time Logistics Scheduling Platform
Mobile-first scheduling app replacing manual phone-based dispatching in oilfield logistics.
Result: 75% faster scheduling turnaround, 80% fewer manual coordination calls on this Business Automation system.
Whether it's a CRM System or an Admin Dashboard, I build for actual daily usage, not demo traffic.
Message me with what's currently slowing your team down: manual process, clunky dashboard, disconnected systems, and I'll tell you exactly what's fixable and what it'll take, free of charge, before you spend anything.
