I will develop a full stack mern web app with react node mongodb
Muhammad Haider
About this gig
Need a complete, production-ready web app built on the MERN stack? Let's build it right.
I'm a senior full-stack engineer with 4+ years shipping production MERN apps React, Node.js, Express, and MongoDB. I build clean, scalable apps with a real backend, a real database, and a UI that works on every screen.
What I build:
- Full-stack web apps & SaaS dashboards
- REST APIs and MongoDB database design
- User authentication & role-based access
- Admin panels and CRUD systems
- Stripe/PayPal payments & 3rd-party integrations
Why work with me:
- Senior-level, maintainable code never templates
- Front-end and back-end built by one engineer
- Clear updates, fast replies, on-time delivery
- 100% of the source code is yours
How it works:
- Message me your idea or requirements first
- I confirm scope & send a custom offer if needed
- You get a working, deployed full-stack app
Note: A "page" = one screen/route. Dashboards or complex pages with heavy logic may count as more message me first so I scope it right.
Let's build something that works send me a message!

Senior full-stack engineer specializing in MERN, Next.js, and React Native. I currently lead development of an AI-powered cybersecurity SaaS that unifies alerts from enterprise security tools and uses AI to investigate them automatically, turning hours of analyst work into minutes.
What I do best: building production SaaS apps end to end, integrating AI/LLM features that actually work, and rescuing broken or half-finished React and Node projects.
Clean code, clear communication, and honest timelines. If your app needs to be built, fixed, or made smarter, let's talk.

FAQ
Do you build both the front-end and the back-end?
Yes — that's the point of this gig. I build the complete app: React front-end, Node/Express backend, MongoDB database, and the APIs that connect them. One engineer, end to end.
Can you add user login and authentication?
Yes. Authentication with secure password handling and role-based access is included in the Premium package, and available as a custom add-on for other tiers.
Can you integrate payments (Stripe/PayPal)?
Yes — add the Payment Integration extra and I'll set up secure checkout with proper webhook handling. Just provide your Stripe or PayPal account.
Do I get the source code?
Always — you own 100% of the front-end and back-end source code on delivery. No lock-in.
Can you finish or fix an existing MERN project?
Yes. I work with existing codebases often — debugging, finishing, or extending them. Send me the repo or a description first and I'll send a custom quote.
Will you deploy it live for me?
eployment is included in Premium. For Basic/Standard, add the Hosting Setup extra and I'll put your full app (front-end, backend, and database) live on a working URL you own.
What do you need from me to start?
A clear description of what you want (or wireframes/designs), the list of features/screens, and any API keys or accounts needed for integrations.
What counts as one "page"?
A page = one screen or route. Dashboards or pages with heavy logic, CRUD, or multiple data states may count as more than one — message me before ordering so I scope it accurately.
