NORRA – Booking Marketplace App: Payments + Voice Calls NORRA is an on-demand marketplace where users book paid voice sessions with "listeners." I designed, built, and shipped the entire product to beta solo — a cross-platform Flutter app (combined user + listener), a Node.js/Express 5 + PostgreSQL REST API, and a Svelte admin panel. Features: • Stripe hold-then-capture payments tied to the booking lifecycle • Twilio VoIP calls with native iOS/Android push handling • Bookings, ratings, reviews, tips, cancel/reschedule • FCM push, scheduled reminders, SendGrid email, PDF receipts • Swagger-documented API, Jest tests, Docker
