APIs & services
REST and GraphQL APIs with Express, Fastify, or NestJS — validated inputs, typed responses, and proper auth.
Backend
Node.js Development Services
Scalable Node.js backends in TypeScript — REST and GraphQL APIs, real-time features, background jobs, and databases — the reliable server layer behind your web app, SaaS, or automation.
What I build
What's included
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
Sound familiar?
- 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 this looks 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 it works
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
Connect your systems and build the APIs behind them — REST and GraphQL, third-party integrations, webhooks, and OAuth 2.0 — so data moves automatically between the tools you already use.
Next.js Development Services
SEO-ready, fast web apps on the Next.js App Router — server components, SSR/SSG/ISR, and built-in metadata and image optimization so pages rank and load quickly.
Full-Stack Development Services
One developer for the whole product — React and Next.js front ends, Node.js APIs, databases, auth, and deployment — so the UI and the API behind it are built as one coherent system, not stitched-together handoffs.
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.
