I built both sides of this product, the API and the administration panel, from the database schema to the last screen. The backend is a modular NestJS application on PostgreSQL with TypeORM migrations, JWT authentication, a granular roles and permissions layer, S3 media storage with magic byte validation, BullMQ queues for transactional mail, Firebase and Expo push notifications, and automatic video transcoding to H.264 so every asset uploaded from a phone stays playable in the browser.

On the frontend I extended a Material UI base into a complete administration suite: dynamic tables with server side search and filters, account validation flows, booking management with QR verification, moderation tools for reported content, a media library, and four analytics dashboards built on raw SQL aggregates with cached responses. The whole stack is deployed with Docker and CI/CD pipelines, with health checks and Prometheus metrics in production.
