I will build a mern web app and react native mobile app for your business


About this gig
Looking for a developer who can build both your web app and mobile app? You're in the right place.
I'm a full stack developer with 4+ years of experience and 50+ completed projects. I specialize in the MERN stack (MongoDB, Express, React, Node.js) and React Native, so you get one developer for your entire product instead of managing two.
What I can build for you:
- Business dashboards and admin panels
- E-commerce web apps and mobile apps
- SaaS platforms (subscriptions, multi-user, payments)
- Booking, delivery, and marketplace apps
- Custom CRM, POS, or inventory systems
- REST APIs and backend services
What you get:
- Clean, scalable, production-ready code
- Responsive design that works on all devices
- Secure authentication (JWT, OAuth, social login)
- Payment integration (Stripe, PayPal, SSLCommerz, bKash)
- Database design (MongoDB or PostgreSQL)
- AWS, or Play Store / App Store
- Free bug fixes after delivery
Why choose me:
- 4+ years of experience, 50+ projects delivered
- Fast communication, daily progress updates
- I write code you can maintain and scale later, not throwaway code
Please message me before ordering so I can understand your requirements and give you an accurate timeline and price.

FAQ
Do you build both the web app and mobile app?
Yes. I work with MERN for web and React Native (Expo) for iOS and Android, so I can deliver both from one codebase strategy.
Will I get the source code?
Yes, you get full source code, and I can push it to your GitHub repo.
Can you work with my existing project?
Yes, I can fix bugs, add features, or refactor existing MERN or React Native projects. Message me with details first.
Do you provide deployment?
Yes, I deploy to Vercel, Railway, Render, AWS, VPS and publish to Play Store and App Store (you provide developer accounts).
What do you need from me to start?
Your requirements, any design files (Figma is ideal), and reference apps or sites you like.
