TECH STACK:ReactNode.jsExpressMongoDBDockerTerraformGitHub ActionsSwagger

EXECUTIVE OVERVIEW & PROBLEM STATEMENT

A production-grade full-stack e-commerce platform built from scratch with a decoupled architecture pairing a responsive React storefront with an Express/Node.js REST API. Designed for high conversion and discoverability, the platform features dynamic multi-image galleries engineered for fast Largest Contentful Paint (LCP) and SEO, persistent cart & wishlist synchronization, comprehensive product catalog filtering, interactive Swagger API documentation, automated two-stage GitHub Actions CI/CD workflows, and AWS cloud infrastructure declared in Terraform.

CORE SYSTEM ARCHITECTURE & DESIGN PATTERNS

Decoupled full-stack architecture with a React SPA client communicating over RESTful JSON with an Express/Node.js backend, backed by MongoDB for flexible catalog schemas, Docker for consistent containerization, GitHub Actions for automated pipelines, and Terraform for AWS infrastructure.

Dynamic multi-image gallery system with responsive picture sets, lazy loading, and optimized metadata for high SEO ranking.

Comprehensive RESTful backend API covering 25+ endpoints for auth, products, categories, cart, wishlist, orders, and reviews.

Interactive Swagger / OpenAPI 3.0 documentation for API contract testing and client integration.

Automated two-stage CI/CD pipeline via GitHub Actions for automated unit testing, linting, Docker image building, and deployment.

Infrastructure as Code (IaC) with Terraform provisioning AWS storage buckets and networking configurations.

KEY ENGINEERING CHALLENGES & ARCHITECTURAL SOLUTIONS

Dynamic Multi-Image Rendering & Core Web Vitals (SEO)

THE ENGINEERING PROBLEM

Product detail pages featuring multiple high-resolution image angles caused slow Largest Contentful Paint (LCP) and high client bandwidth consumption.

ENGINEERED RESOLUTION

Engineered dynamic multi-image carousels with responsive image breakpoints, priority preloading for the primary hero shot, and deferred thumbnail loading, maintaining sub-second render times and optimal SEO indexability.

Automated Two-Stage CI/CD Deployment

THE ENGINEERING PROBLEM

Manual deployment and inconsistent local runtime environments risked shipping breaking regressions and configuration drift.

ENGINEERED RESOLUTION

Built separate CI (Continuous Integration: automated lint, test, build validation) and CD (Continuous Deployment: Docker image creation and deployment orchestration) workflows in GitHub Actions.

Infrastructure as Code with Terraform

THE ENGINEERING PROBLEM

Manually configuring cloud resources on AWS is error-prone, hard to audit, and challenging to replicate across staging and production environments.

ENGINEERED RESOLUTION

Authored modular Terraform infrastructure scripts declaring AWS S3 buckets for product image assets, bucket access policies, and environment configurations in version-controlled code.
