Kitchen sync
Restaurant chains needed digital menus and kitchen coordination without replacing entire POS stacks. We shipped a multi-tenant SaaS with QR ordering, real-time ticket flow, and owner analytics — cutting order processing time by 30% during peak hours.

Context
Chains operated on paper menus and phone-heavy coordination between floor and kitchen.
Owners lacked cross-branch visibility into throughput and peak bottlenecks.
Product goal: one SaaS tenant per brand with branch-level menus and permissions.
The challenge
Fragmented operations slowed orders, created kitchen backlog, and made scaling new branches a manual, error-prone process.
The response
Built end-to-end multi-tenant SaaS with dynamic QR menus, order state machine, kitchen display views, and centralized owner dashboards powered by Firebase real-time updates.
How it unfolded
01
Peak-hour delays and static menus hurt revenue; owners had no single view across locations.
02
QR as the entry point; strict order lifecycle; kitchen UI as a first-class persona.
03
Shipped tenant onboarding, menu publish flow, KDS screens, and branch analytics in phased releases.
04
30% faster processing, reliable kitchen sync, and scalable multi-branch rollout.
Architecture decisions
Explicit states (placed → preparing → served) prevented race conditions between customer, server, and kitchen views.
Low-latency push to kitchen devices without overloading the core API during rush periods.
Versioned menu publishes avoid breaking in-flight orders when prices or items change.
