Fintech Site & Portfolio Dashboard

I need an end-to-end fintech web application that feels modern and clean from the first screen. On the public-facing side, visitors should see real-time prices for a chosen financial instrument, broken down by exchange in an easy-to-scan layout.

Once a user creates an account and passes two-factor authentication, the private dashboard appears: here they can view their current portfolio with the total value calculated and refreshed automatically. Behind the scenes I’ll need the usual CRUD for user data and positions, plus an admin panel where I can add new products that shoppers can drop straight into a cart.

Payments must support both standard credit/debit cards and cryptocurrency (in Phase 2). If you already have experience integrating PhonePe, razorpay etc, or similar APIs, —smooth checkout flow and secure handling of sensitive data are crucial.

Deliverables
• Responsive frontend (React, Vue, or similar) showing live multi-exchange pricing
• Secure backend with 2FA login, user portfolio calculation, and admin product management
• Cart/checkout module wired to card and crypto gateways
• Clear setup docs and any seed data or environment variables needed for me to run the project locally and on production

Please highlight relevant fintech or payment projects you’ve shipped before, and the tech stack you propose to use so we can move ahead quickly.
