Backend & API Development

Scalable backend systems, REST APIs and databases using Node.js, Express and MongoDB.

What this involves

The backend is where data is validated, stored and protected. That means REST endpoints with predictable shapes, schema validation on anything arriving from a client, authentication that holds up across routes, and MongoDB collections designed around how the application actually queries them. Where an application needs updates to arrive as they happen, WebSockets or Socket.io carry them instead of polling.

What it includes

  • REST API design with Node.js and Express
  • MongoDB schema design and Mongoose models
  • Request validation with Zod
  • Authentication and authorisation with JWT
  • Real-time channels using WebSockets or Socket.io
  • Third-party API integration, including Stripe, Cloudinary and OpenAI
