E-Commerce Platform with Microservices

Overview

A microservice-ready e-commerce platform built end to end — a RESTful Spring Boot backend, a responsive React storefront, and a MySQL data layer — structured so individual services can scale or be extracted independently as the system grows.

The problem

Most personal e-commerce projects hard-code a single monolithic backend that can’t demonstrate how a real storefront scales. The goal was something with an actual service-boundary story, not just a CRUD app with a shopping cart.

Approach

I implemented the backend as RESTful Spring Boot APIs, with the MySQL schema specifically reworked — indexes and query patterns — to cut response times by roughly 30%. The React frontend covers registration, login, and the core product browsing/purchase flows. The API layer is structured in independently deployable modules so it can decompose into separate microservices without a rewrite.

Architecture

1. Spring Boot REST API layer, structured for microservice decomposition
2. MySQL data layer with optimized schema and indexing
3. React frontend — auth, product catalog, and cart flows

Results

Achieved roughly 30% faster query response times through schema and indexing optimization, with complete registration-to-purchase user flows on the frontend.
