Assemble a burger by dragging ingredients straight into the constructor. React DnD manages the drag sources, drop targets, and live reordering, so composing and rearranging a build feels natural and responsive.

Global state is centralised with Redux and @reduxjs/toolkit, keeping the cart, ingredients, and order flow predictable, while the React Context API powers in-app translations for a fully multilingual interface.

A two-layer test suite keeps changes safe: Cypress drives end-to-end flows through the real UI, while Jest covers units and reducers — together guarding against regressions on every commit.

Registration and login are secured with JSON Web Tokens. Tokens are stored securely and attached to protected requests, with guarded routes that redirect unauthenticated users away from private pages.

A persistent WebSocket connection streams the public order feed and the user's personal order history in real time, so statuses update instantly with no manual refreshes or polling.

Continuous delivery ships the app to GitHub Pages, turning every push to the main branch into an automated build and deploy for fast, repeatable releases.
