numq/ecommerce-backend

This system is an e-commerce backend platform built on a microservices architecture, where each domain (account, cart, catalog, order, etc.) is an independent service communicating via gRPC. It provides core commerce capabilities including user authentication, product and category management, shopping cart operations, order processing, and search functionality. The infrastructure relies on MongoDB for persistent storage, Redis for caching and session management, and message queues for asynchronous updates.

How it got here

2022 · Microservices scaffolding and core domain implementation

This period focused on establishing the foundational infrastructure and implementing the initial versions of key microservices, including authentication, cart, catalog, category, and delivery. The work involved setting up build systems, dependency management, and gRPC-based service contracts, while also introducing domain-specific logic and data persistence for each module.

2023 · microservice architecture implementation

This period focused on building out the core microservice infrastructure, introducing gRPC-based services for account, profile, order, and confirmation management. The work established a consistent pattern of using MongoDB or Redis for persistence, implementing authentication interceptors, and containerizing services with Docker. Additionally, supporting services for search, promo codes, and a central API gateway were launched to complete the distributed system's foundation.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 4 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit ef9536cd62 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.19. Score the same commit under that rubric and you get the same number.
