Restaurant Management System
Overview
A comprehensive restaurant management platform built with micro-service architecture, designed to streamline operations from order management to inventory tracking, staff scheduling, and analytics.
The Challenge
Modern restaurants need integrated systems that handle:
Real-time order processing across dine-in, takeout, and deliveryInventory management with low-stock alertsStaff scheduling and role-based permissionsFinancial reporting and analytics dashboardsMulti-location supportArchitecture
Micro-Service Design
Each domain was isolated into its own service:
Order Service — Real-time order lifecycle management with WebSocket updatesInventory Service — Stock tracking, supplier management, and automated reorder alertsStaff Service — Employee scheduling, attendance, and access controlAnalytics Service — Aggregated reporting across all servicesNotification Service — Push notifications, SMS, and email alertsCommunication Patterns
Synchronous REST APIs for queries and CRUD operationsAsynchronous message queues (Kafka) for event-driven workflowsAPI Gateway for routing, authentication, and rate limitingDatabase Strategy
Each service owns its database (Database per Service pattern):
Order Service: MongoDB (flexible document structure)Inventory: PostgreSQL (relational integrity for stock)Analytics: Redis for caching + time-series dataResults
15+ features delivered on scheduleHandles peak dinner rush loads effortlesslyIndependent deployment cycles per serviceReduced operational overhead for restaurant managersKey Takeaways
Start with a modular monolith if your team is smallInvest in observability early — distributed tracing is essentialDefine clear API contracts between servicesAutomate CI/CD for each service independently
