Quick answer

What is NestJS and when should you use it?

NestJS is a framework for building server-side applications on Node.js with TypeScript. It gives a back end a clear structure — modules, controllers, services and dependency injection — which keeps large APIs consistent and testable as the team grows. Plain Node.js suits small services; NestJS suits APIs and platforms that will keep growing.

  • TypeScript, modular and testable
  • REST, GraphQL and WebSocket APIs
  • PostgreSQL, MongoDB and Redis

What we build

Node.js back-end development services

Server-side work that rarely gets noticed — because it simply keeps working.

  • Custom back-end development

    The server side of your web or mobile app: data, business rules, authentication and permissions.

    • Node.js
    • NestJS
    • TypeScript

  • REST and GraphQL APIs

    Well-documented, versioned APIs your apps and partners can rely on.

    • REST
    • GraphQL
    • OpenAPI
    API & integrations

  • Microservices architecture

    Services split where it helps, with message queues, events and clear boundaries.

    • Microservices
    • Queues
    • Events

  • Real-time applications

    Chat, live dashboards, notifications and collaboration features over WebSockets.

    • WebSockets

  • Databases and data modelling

    PostgreSQL, MySQL or MongoDB schemas designed for your data, with Prisma or TypeORM and safe migrations.

    • PostgreSQL
    • MongoDB
    • Prisma

  • Background jobs and integrations

    Scheduled tasks, queues and third-party integrations — payments, email, CRMs and ERPs.

    • BullMQ

Ways to work

Three ways to build your back end

Fixed-price builds or a dedicated team, always with a clear architecture plan first.

  • Start lean

    API for an MVP

    A focused back end for a first product version, ready to grow.

    • Data model
    • Auth and roles
    • Core API
    • Deployment

  • Most chosen

    Custom NestJS platform

    A complete, documented back end for a web or mobile product.

    • Architecture plan
    • REST or GraphQL API
    • Jobs and integrations
    • Tests and CI

In every build

What every back-end project includes

  1. TypeScript and a documented architecture
  2. API documentation with OpenAPI
  3. Authentication and role-based access
  4. Input validation and security headers
  5. Unit and integration tests
  6. Logging, monitoring and alerts
  7. Docker and a CI/CD pipeline
  8. Code you own and 30 days of post-launch fixes

How it works

From data model to production

Back ends are built on early decisions, so architecture comes first and every sprint is tested.

  1. Free 30-minute call

    Discovery

    Data, users, integrations and expected load, talked through with your team.

  2. Within 48 hours

    Architecture & quote

    Architecture, scope, milestones and price in writing.

  3. Weekly demo builds

    Build & test

    APIs built in sprints with tests, documentation and a staging environment.

  4. 30 days of fixes

    Deploy & monitor

    Production deployment with logging, alerts and a handover to your team.

Straight answers

Questions worth asking Questions worth asking

The things brands actually ask us before a build — answered properly, including the times the answer is that you do not need us.

  • Is Node.js good for back-end development?

    Yes. Node.js handles many simultaneous connections efficiently, which suits APIs, real-time features and microservices, and using TypeScript on both front and back end lets one team work across the whole product.

  • NestJS or Express?

    Express is minimal and flexible, which suits small services. NestJS adds structure, dependency injection and built-in support for testing, validation and GraphQL — the better choice for back ends that will grow or be worked on by several developers.

  • Which databases do you work with?

    Mainly PostgreSQL, MySQL and MongoDB, with Redis for caching and queues. We choose based on your data and how it will be queried.

  • How much does Node.js development cost?

    It depends on the scope of the API, the integrations and the expected load. After a short call we send a fixed, itemised quote, or a monthly price for a dedicated team.

  • Can you improve the performance of our existing API?

    Yes. We profile the API under realistic load, then fix slow queries, add caching and remove bottlenecks, measuring each change.

  • Can I hire dedicated Node.js developers?

    Yes. Our back-end developers can join your team on a monthly plan, working in your tools and following your processes.
