APIs & services
REST and GraphQL APIs with Express, Fastify, or NestJS — validated inputs, typed responses, and proper auth.
Node.js development provides the server-side APIs, real-time services, background jobs, and database access used by web and SaaS products. It is intended for teams building a new backend or improving an existing service that needs clearer architecture, authentication, queues, or live updates.
What I build
What is included in Node.js development?
Real-time features
WebSockets with Socket.io for chat, live dashboards, and notifications, backed by Redis pub/sub.
Background jobs & queues
BullMQ + Redis workers for emails, report generation, and any slow task that shouldn't block a request.
Databases & data access
PostgreSQL or MongoDB with Prisma, migrations, and query design that survives real load.
Problems this solves
What problems can Node.js development solve?
- A synchronous endpoint that generates a report and times out under load.
- A monolith with no separation between routes, validation, and business logic.
- A product that needs live updates but polls the server every few seconds instead.
- APIs with no authentication, validation, or rate limiting exposed to the internet.
Example use cases
What does Node.js development look like in practice?
Real-time notifications
Added a Socket.io + Redis layer so users saw updates instantly instead of refreshing, without hammering the database.
Offloaded heavy work
Moved PDF and email generation into BullMQ workers, taking those requests from 30-second timeouts to instant responses.
GraphQL aggregation layer
Built a GraphQL API that stitched three internal REST services into one typed schema for the frontend.

Process
How does Node.js development work?
01
Design the API
Model data, endpoints, and auth as a clear contract.
02
Build & test
Typed services with validation and automated tests.
03
Integrate
Connect databases, queues, and third-party APIs.
04
Deploy & monitor
Ship with logging, environments, and docs.
Node.js is the backend half of my full stack development work, and it's what powers most of my API integration services — the two usually ship together.
Related services
API Integration Services
API integration connects applications so they can exchange data and trigger actions without manual transfer. It is intended for teams that need a custom API, a third-party service connection, webhook processing, or a secure partner-facing interface.
Next.js Development Services
Next.js development uses React with server rendering, static generation, route handlers, and the App Router to build websites and web applications. It is intended for teams whose product needs search-visible pages, server-rendered content, integrated backend logic, or content managed through a CMS.
Full-Stack Development Services
Full-stack development covers the frontend, backend, database, authentication, integrations, and deployment of a web product. It is intended for teams that want one developer to own these connected layers or complete an existing application end to end.
FAQ
Questions, answered
- Express, Fastify, or NestJS — which do you use?
- Express or Fastify for lean services and APIs; NestJS when a larger app benefits from its structure and dependency injection. I choose based on team size and project complexity.
- REST or GraphQL for my API?
- REST for straightforward CRUD and public APIs; GraphQL when clients need flexible queries or you're aggregating several data sources. I'll recommend based on how the data is consumed.
- Can you build real-time features like live updates or chat?
- Yes — with WebSockets (Socket.io) and Redis pub/sub for presence, chat, and live dashboards that scale across instances.
- How do you handle slow or scheduled tasks?
- With a job queue (BullMQ on Redis) and workers, plus cron for scheduled jobs — so long-running work never blocks the API response.
- Are you a Node.js development company or an individual developer?
- An independent Node.js developer — a specialist you work with directly, without agency layers or overhead.
