Build me a full stack banking web app that feels like professional financial software.

I want a clean dashboard where a user can see their current account balance, account activity, and transaction history, with the balance calculated correctly from double entry bookkeeping. The app should support multiple currencies, pulling exchange rates from an external API, and it should work in English, German, and Polish.

Make it look polished and modern, responsive on desktop and mobile, and usable as a PWA. Include the usual banking style UI with clear tables, charts or summaries if they fit, and smooth navigation. Add proper consent handling for cookies and Google Analytics in a GDPR friendly way.

Use a React frontend and a Node.js backend with a REST API and a PostgreSQL database. If you need to, look up current docs online while building it. Keep the code organized and maintainable, and make the experience feel like a real banking product rather than a demo.
