I will build a full stack mern or nextjs web application


About this gig
Full stack developer with 4+ years building production web apps from UI to database.
I'm Muhammad Arsalan Qadir, a full stack JavaScript developer specializing in React, Next.js, and Node.js. Over the past 4 years I've built and shipped real, live products not just tutorials including a marketplace platform with Stripe/PayPal checkout, a real-time inspection app with chat and Google Maps, and a multi-role admin portal with CSV bulk uploads and push notifications.
What I can build for you:
- Responsive, SEO-friendly front ends in React.js, Next.js, or Angular
- REST APIs and backend logic in Node.js / Express
- Database design with MongoDB
- State management with Redux / Redux Toolkit / Context API
- Real-time features with Socket.io
- Payment integration: Stripe, PayPal, Braintree
- Auth: Firebase, Okta, JWT
- Admin dashboards with role-based access (super admin / admin / manager)
Why work with me:
- I handle both frontend and backend, so nothing gets lost in translation between two freelancers
- I've worked directly with clients and stakeholders, not just in isolated dev teams I communicate clearly and give realistic timelines
- Clean, maintainable code with attention to performance and SEO
