Ecommerce Microservices Platform

A Production-Grade Dockerized Microservices Architecture

Microservices Architecture — Each service has its own database, Dockerfile, and independent deployment

Docker Compose Orchestration — 14 containers (6 databases + 6 backend + 1 UI + 1 gateway)

Multi-Stage Docker Builds — Optimized production images with non-root users

PostgreSQL per Service — Database-per-service pattern with seed data and health checks

Nginx API Gateway — Rate limiting (30 req/min API, 5 req/min login), gzip compression

Inter-Service Communication — REST over Docker internal DNS with service discovery

Order Orchestration — Order creation triggers: Inventory reservation → Profile lookup → Shipment creation

JWT Authentication — Bcrypt password hashing + JWT tokens

Inventory Transactions — Row-level locking to prevent race conditions

React SPA — Modern UI with Tailwind CSS, routing, cart, auth context
