01How it looks
Five entry points, one order.
The first screen is a screenshot of the public website. The others are schematic views of the platform's parts, with made-up order numbers.
- 01 / 05
Public website
Menu, locations and ordering, open to everyone. The full menu with categories, search and filters, built for phones.
- 02 / 05
Customer PWA
Installs in one click from the browser and is also published as an Android app in Play Console. Cart, address book, loyalty credits and order tracking.
- 03 / 05
Restaurant panel
It stays open on a wall-mounted tablet next to the grill. A new order sets off an audible siren, so the cook won't miss it even when the kitchen is loud.
- 04 / 05
Platform admin
Daily counters, drivers online, the latest orders and revenue. From the same panel: products, categories, add-ons, ratings, credits and reports per location.
- 05 / 05
Driver app
The driver sees orders ready for pickup, accepts them with a tap and marks them as delivered. The customer's rating closes the loop.

02See the stack
Five roles, one source of truth.
The customer orders in the PWA, the kitchen sees the order with an audible siren on the restaurant panel, the driver picks it up on their phone, and the admin follows it all live. Same database, different role.
02
Customer PWA
An installable mobile app. Cart, address book, loyalty credits, push notifications, order tracking. Android TWA in Play Console.

Platform admin
Bird's-eye view: every order, every product, every shop, every driver. Categories, addons, hero slides, reports, ratings, credits.

05
Driver app
Phone first. New order notifications, a route on the map, picked up / delivered status, customer rating. One driver per location, easy to expand.
dostava.leskovackikutak.rs
06
Shared API
A REST endpoint that the four apps and the website sync with. One source of truth: the same product, the same order, four perspectives.

03Under the hood
Boring tech, exciting business.
01
Backend
PHP 8.5 with PDO and MariaDB. Custom session auth with roles (admin / restaurant / driver / customer). PSR-style includes, no framework bloat.
02
Frontend
Vanilla JS, no SPA framework. A Service Worker per panel for offline and push. A web manifest for installation. Android TWA for the customer PWA.
03
Real-time
SSE with polling as a fallback. When a customer orders, the kitchen panel sounds the siren in under a second. When the driver picks up the order, the customer sees the status right away.
04
Security
bcrypt, CSRF tokens, a separate login per role, rate limiting on auth endpoints, CSP and HSTS preload, A+ on SSL Labs.
05
Delivery zones
Polygon zones per location. The customer's address is checked against the location's zone, and the price follows distance bands. The RGZ street database is integrated.
06
Loyalty and referrals
A built-in credit ledger: every order earns credits by tier, and referrals give a bonus on the first order. Promo codes and time-limited campaigns.

Delivery ecosystem for your brand.
If you'd rather not hand a share of every order to a delivery platform, a system like this takes orders through your own site. The same model works for pizzerias, sushi, grills and bakeries.
