Full-Stack Web & Mobile Application

Job ID: 40451207

Budget: ₹12,500 – ₹37,500 INR

I’m kicking off an end-to-end build that must run smoothly on the web and on native Android / iOS. The stack is already settled: React.js with Bootstrap for the browser front end, React Native (Flutter is acceptable if you can justify it) for the mobile twin, and a Node.js + Express.js back end wired to MongoDB.

Core scope
• Design the data model, stand up the REST API layer, and wire in JWT-based authentication and role-based authorization.
• Deliver an interface that adjusts gracefully to every screen size, stays snappy, and follows solid UX patterns.
• Implement real-time notifications, support in-app purchases on mobile, and make sure the whole flow remains secure.
• Keep the codebase clean, modular, and fully commented so future contributors can ramp up quickly.

Deployment & hand-off
I’ll need Dockerized builds, CI/CD scripts (GitHub Actions or similar), and basic post-launch monitoring so I can keep an eye on performance and error logs.

Selected must-haves
- User authentication and authorization
- Real-time notifications
- In-app purchases

When you reply, focus on your direct experience shipping React / React Native (or Flutter) apps at scale, especially anything involving secure payment flows or push notification systems. A concise overview of past projects that mirror this tech stack will help me shortlist quickly.
