Comprehensive Web & Mobile Platform Development

I need a full-cycle build of a modern platform that works seamlessly on the web and on both iOS and Android devices. The job covers everything from UX-driven front-end screens to a secure, scalable back end, topped off with an intuitive admin panel.

Core features
• Three distinct roles—Admin, Regular user and Guest—each with the right permissions, onboarding flows and dashboards.
• Payment module that processes credit/debit cards and UPI from day one, with the codebase kept flexible enough to slot in additional gateways later if we choose.
• Real-time reports and analytics that the admin team can filter, export and act on quickly.
• Clean, responsive UI that maintains 60 fps performance across phones, tablets and desktop browsers.
• Production-grade deployment (CI/CD, staging, monitoring, rollback) so the system can scale without drama.

Deliverables
1. Web app (React, Vue or similar) fully responsive.
2. Native or cross-platform mobile apps for iOS and Android.
3. REST/GraphQL API plus database, built with an emphasis on security and future growth.
4. Admin portal with user management, role controls and reporting.
5. Deployment scripts/documentation for cloud hosting.

When you respond, please include:
• A link to comparable projects in your portfolio.
• Your recommended tech stack and why it fits.
• A high-level timeline with key milestones.
• Your cost breakdown and payment schedule.

I’m ready to move quickly once the right partner is found, and I’ll be available for daily stand-ups or weekly demos—whatever keeps the project flowing smoothly.
