Hire a Node.js Developer
Hire a Node.js developer from Bracket Coder when you need a backend that handles many concurrent connections without falling over. We build event-driven services on Node.js and its ecosystem, including Express, Fastify, NestJS, and Socket.IO, for REST and GraphQL APIs, real-time features, third-party integrations, and serverless functions. Our team are senior engineers led by Sharan Sifat, and we treat your backend as something we will have to maintain, not just ship.
Node.js is a strong fit when your product is I/O-heavy: chat and presence, live dashboards, notifications, streaming uploads, or an API gateway that fans out to other services. It shares a language with your React or Next.js frontend, which keeps types and validation logic consistent across the stack. We also know where Node is not the right tool, and we will tell you when a job belongs in a worker queue, a background process, or a different runtime altogether.
APIs built on Node.js
Most of what we build in Node.js is an API of some kind. We design REST and GraphQL endpoints with clear resource boundaries, request validation with Zod or Joi, and consistent error handling so clients get predictable responses. Authentication is handled with JWTs, sessions, or OAuth depending on your case, and we add rate limiting, input sanitisation, and structured logging from the start rather than bolting them on later. We write the service in TypeScript so the contract between routes, database, and callers is checked at build time. Tests cover the routes that matter, such as auth, payments, and anything that mutates data, using Jest or Vitest with Supertest against a real test database.
Real-time features with WebSocket
Real-time is where Node.js earns its place. We build WebSocket features, including live chat, typing and presence indicators, order and delivery status, collaborative editing, and dashboards that update without a refresh, using Socket.IO or the native ws library. For anything beyond a single server, we back the socket layer with Redis pub/sub so connections stay in sync across instances and survive a deploy or a restart. We handle the parts people forget: reconnection with backoff, authenticating the socket handshake, room and namespace design, and backpressure when a client is slow. If your app already speaks HTTP, we can add a real-time channel alongside it without rewriting what works.
Integrations, webhooks, and serverless
A lot of backend work is connecting systems. We integrate payment gateways such as Stripe, email and SMS providers, storage and CDNs, CRMs, and internal APIs, with webhook endpoints that verify signatures and process events idempotently so a retry never double-charges or double-sends. Slow or bursty work goes onto a queue, typically BullMQ on Redis, rather than blocking a request. When it fits, we deploy Node functions to serverless platforms like Vercel, AWS Lambda, or Cloudflare Workers, which suits webhook handlers, scheduled jobs, and spiky traffic you do not want to run a server for around the clock. We advise on cold starts and connection pooling so serverless does not quietly hurt your database.
How hiring a Node.js developer works
You can hire a Node.js developer from us for a single API, a real-time feature added to an existing product, or an ongoing engagement where we own a service end to end. We start with a short scoping call to understand your data model, traffic, and deadlines, then send a written plan with milestones so you can see what ships and when. You get code in your repository, review through pull requests, and documentation for how to run and deploy it. Node work often pairs with our Next.js, Django, and Flutter teams, so if your project also needs a frontend or a mobile client, the same group can carry it rather than handing you off.

Frequently asked questions
Which Node.js frameworks and tools do you use?+
It depends on the job. Express and Fastify for lean REST APIs, NestJS when a larger app benefits from structure and dependency injection, and Socket.IO or ws for WebSocket work. We default to TypeScript across all of them and lean on Redis, BullMQ, and Prisma or an ORM that fits your database.
Can you add real-time features to an app I already have?+
Yes. We can add a WebSocket layer to an existing Node, Django, or other backend, wire it to your frontend, and back it with Redis pub/sub so it scales past a single server. We will not rewrite working code just to introduce real-time.
Is Node.js the right choice for my backend?+
Node is excellent for I/O-heavy, concurrent, and real-time workloads, and for sharing one language with a React or Next.js frontend. It is a weaker fit for heavy CPU-bound computation. We will say so during scoping and suggest a queue, a worker, or a different runtime when that is the honest answer.
Do you handle deployment and serverless?+
Yes. We deploy Node services to traditional servers or to serverless platforms such as Vercel, AWS Lambda, and Cloudflare Workers, and we set up CI, environment configuration, and the connection-pooling and cold-start details that serverless introduces.
