API work stalls when the same few engineers are asked to build new endpoints and keep production running.

What You Can Build With Node.js

REST and GraphQL APIs

Versioned, documented endpoints with validation, authentication and rate limits.

Tech Stack

  • Node.js
  • TypeScript
  • Fastify
  • PostgreSQL

Outcome

Web and mobile teams build against a contract that does not shift under them.

Node.js is an OpenJS Foundation project with a published release schedule, in which even-numbered versions become long-term support lines.

  • OpenAPI

Express for what already exists, Fastify or NestJS where structure and speed matter.

  • Express
  • Fastify
  • NestJS

Relational modelling, indexing and migrations, plus document stores where they fit.

How Node.js Has Evolved

  1. 2009

    First releaseLaunch

    Ryan Dahl presented Node.js, pairing the V8 engine with non-blocking I/O.

  2. 2015

    Node.js 4Merged

    The io.js fork merged back and the project moved under a foundation.

  3. 2017

    Node.js 8Async/await

    Async functions became available in a long-term support line.

  4. 2022

    Node.js 18Fetch

    Added a global fetch API and the node:test module.

  5. 2023

    Node.js 20Test runner

    The built-in test runner became stable and an experimental permission model was added.

  6. 2024

    Node.js 22WebSocket

    A built-in WebSocket client and a stable watch mode.

When Node.js Is The Right Choice

Choose Node.js when

  • The work is mostly I/OCalling databases, APIs and queues is where non-blocking I/O performs well.
  • Your front end is already TypeScriptOne language on client and server means shared types and easier moves between teams.
  • You need live connectionsLong-lived WebSocket connections are inexpensive to hold open.
  • You want small services shipped quicklyThe package ecosystem covers most integrations, so less is written from scratch.

Consider something else when

  • The workload is CPU heavyVideo encoding or large numerical jobs block the event loop. Go, Rust or Java handle these better.
  • You need mature data science librariesPython has the deeper ecosystem for modelling and analysis.
  • You rely on strict compile-time guaranteesTypeScript helps, but its types are erased at runtime. A compiled language may suit better.
  • Dependencies must be kept to a minimumNode.js projects tend to pull in many packages, which adds audit work in regulated settings.

Why CTOs Choose Us

Screening includes reviewing and extending an existing Node.js API, not a whiteboard exercise.

You interview the developer and read their code before any contract.

Work happens in your repository, your CI and your ticket board.

Each developer works for one client at a time.

Month-to-month terms, no exit fee, and a replacement if the fit is wrong.

AI In Delivery

Where coding assistants help, and where a person decides.

  • Used for speed

    Boilerplate, test scaffolding and first drafts of documentation.

  • Always reviewed

    Every change is read and approved by an engineer before it merges.

  • Never given secrets

    Credentials and client data stay out of prompts. Your policy on AI tools applies.

Security And IP

What we enforce on every engagement.

  • IP assignment

    All work product is assigned to you in the contract.

  • NDA first

    Signed before anyone sees your code.

  • Least privilege

    Access limited to what the task needs.

  • Clean exit

    Access revoked and handover documented when work ends.

Both. Most current work is in TypeScript, and they can maintain older JavaScript services or help migrate them file by file.

Express, Fastify and NestJS are the most common. Tell us what you run and we shortlist for it.

Many have React or Vue experience. If you need a full-stack profile, say so at the start and we shortlist for both sides.

An NDA is signed before anyone sees your code. All code and IP belong to you, and work is committed to your repositories.
