Overview

A production-structured REST API for a blog platform, built during the M-Knows Consulting Backend API Development Bootcamp in 2023. Implements full CRUD, authentication, email notification, and API documentation.

Context

Bootcamp project at M-Knows Consulting — Backend API Development program. Role: Backend Developer. Year: 2023.

Responsibilities

Designed and implemented an MVC architecture with Node.js, Express, and TypeScript.
Integrated Sequelize ORM with PostgreSQL for relational data management.
Built JWT-based authentication (register, login, token refresh, protected routes).
Implemented input validation and structured error handling.
Integrated email notification using a third-party email service (Nodemailer).
Set up structured logging with Winston.
Produced API documentation using Postman and a swagger.yaml specification.

Architecture

Three-layer MVC: controllers handle HTTP routing, services contain business logic, and models map to PostgreSQL via Sequelize. Authentication middleware guards protected routes, and logging middleware captures request/response metadata.

Key Engineering Decisions

Chose a layered MVC split so routing, business logic, and data access stay independently testable.
Used JWT with refresh tokens to keep the API stateless while supporting longer sessions.
Centralised validation and error handling so endpoints return consistent error shapes.
