Five roles, one source of truth.

Customer places the order on the PWA → the kitchen sees it with an audible siren on the restaurant panel → driver picks up the assignment on the phone → admin follows every step in real time. Same database, different role.

Under the hood

Boring tech, exciting business.

Backend

PHP 8.3 with PDO + MariaDB. Custom session-based auth with role flags (admin / shop / driver / customer). PSR-style includes, no framework bloat.

Frontend

Vanilla JS — no SPA framework. Service Worker on each panel for offline + push. Web manifest for install. Android TWA wrap of customer PWA.

Real-time

Server-sent events + polling fallback. New order on the customer side → kitchen panel hears the siren in <1s. Driver pickup → customer sees the status flip instantly.

Security

bcrypt password hashing, CSRF tokens, separate login pages per role, rate limit on auth endpoints, CSP + HSTS preload, A+ SSL Labs.

Delivery zones

Per-shop polygon-based delivery zones. Customer address looked up against the shop's zone, price calculated per distance band. RGZ street database integrated.

Loyalty + referrals

Built-in credit ledger — every order earns tier-based credits, referrals trigger first-order bonus. Promo codes, time-bound campaigns.

Live deployment

Open any of the five entry points.

Running a restaurant chain?

Privacy Policy

Last updated: 2026-09-18.

This document explains, in plain language, what data we collect, why we collect it, and how we keep it. No fine print.

Terms of Service

Last updated: 2026-09-18.

These terms describe how we work together. They're written in plain language — if anything is unclear, just ask.

Who provides the service

Sites and apps are built by D. Svilenković, contact: dimitrije@svilenkovic.com, +381 61 224 8989.

What we do

We build websites, web and desktop apps, online stores, Excel automation, appointment booking, system integrations, hosting and maintenance.

How we agree on work

  1. You tell us what you need. The conversation is non-binding.
  2. We send you a quote with price and timeline.
  3. When you confirm, we start development.

Price and payment

The price is fixed and agreed upfront. The invoice is issued only after you confirm you're happy with the result. If the scope changes significantly, we agree on the new price before continuing.

Timelines

We give a deadline in the quote and stick to it. If we need material from you (images, text, access), please send it on time — the deadline depends on it.

Revisions

Small revisions are included and done at no charge. Larger changes that go beyond the original scope are agreed separately.

Ownership

Once paid, everything we built is yours. You can use it, change it, or move it to another developer without involving us.

Hosting and maintenance

The first year of hosting and maintenance is included. After that, if you want to continue, we agree on a support plan. You can move the site to another host at any time.

Liability

We strive for everything to work flawlessly, but bugs happen. As soon as you report one, we fix it as fast as possible. Our liability is limited to the amount paid for the project.

Cancellation

You can cancel at any time. You pay only for the work done up to that point, and receive all the materials and code you've paid for.

Disputes

If a disagreement arises, we'll first try to resolve it by talking. If that fails, the law of the Republic of Serbia applies and the court at the provider's seat is competent.

Changes to these terms

These terms may be updated. The last-updated date is shown at the top — you can always see what currently applies.
