Restaurant POS SaaS

A multi-tenant operational platform for restaurants covering ordering, inventory, and administration.

Role: Full-stack engineering across backend, operations, and mobile-integrated workflows.

Problem solved

Restaurant teams needed one operational system instead of disconnected ordering, inventory, and staff tools.

Solution

Built a modular platform with tenant-aware workflows, admin dashboards, and integration hooks for business growth.

Architecture overview

Backend services expose operator-focused APIs, while admin interfaces prioritize fast navigation and low-friction transaction handling.

Database design

Structured multi-tenant data boundaries around restaurants, orders, inventory, customers, and staff actions to preserve reporting clarity and operational isolation.

API design

REST endpoints handled ordering, reporting, inventory movements, and staff flows, with WebSocket-driven updates for time-sensitive operational screens.

Lessons learned

  • Operational software improves fastest when the team maps real service timing first.
  • Real-time features need clear fallback behavior, not just socket updates.
