Backend

Node.js backends
that never go down

Express, Fastify, NestJS, or Hono — we build Node.js APIs and services that handle traffic spikes, process webhooks at scale, and keep your infrastructure costs in check.

What we build

Backend services we build

From REST APIs to event-driven architectures, our Node.js expertise covers the full backend spectrum.

01 / APIs

REST & GraphQL APIs

Type-safe APIs with automatic OpenAPI documentation, request validation, and response serialization — built for both internal teams and third-party consumers.

  • Express / Fastify / Hono route handlers
  • Zod schema validation with auto-generated docs
  • GraphQL with code-first schema (Pothos)
  • API versioning & deprecation strategies
02 / Real-Time

Real-Time & WebSockets

Live dashboards, collaborative editing, and push notifications via WebSockets and Server-Sent Events — with horizontal scaling across multiple nodes.

  • Socket.IO with Redis adapter for clustering
  • Server-Sent Events for unidirectional streams
  • Presence tracking & connection management
  • Rate limiting & connection throttling
03 / Queues

Background Jobs & Queues

Reliable async processing for emails, reports, data imports, and anything too slow for a request-response cycle.

  • BullMQ with Redis for job processing
  • Retry policies with exponential backoff
  • Dead letter queues & failure alerting
  • Priority queues & rate-limited workers
04 / Auth

Authentication & Security

JWT, OAuth 2.0, SAML — we implement auth that meets enterprise security requirements without creating friction for your users.

  • JWT with refresh token rotation
  • OAuth 2.0 / OIDC integration (Auth0, Clerk)
  • RBAC & ABAC authorization middleware
  • Rate limiting, CORS, helmet, and CSP headers

Use cases

Node.js use cases

Payment processing API

PCI-compliant payment gateway integration handling Stripe, Braintree, and wire transfers with idempotent retries and webhook reconciliation.

Webhook ingestion service

High-throughput webhook processor receiving events from Shopify, Stripe, and Twilio — deduplicating, validating, and fanning out to downstream services.

Notification service

Multi-channel notification engine (email, SMS, push, in-app) with template management, delivery tracking, and user preference respecting.

File processing pipeline

Async pipeline for document upload, virus scanning, thumbnail generation, and OCR extraction — handling 10GB+ files with streaming.

API gateway

Centralized API gateway with rate limiting, API key management, usage analytics, and request/response transformation for microservice architectures.

IoT data ingestion

MQTT-to-REST bridge ingesting telemetry from 50k+ IoT devices, aggregating time-series data, and triggering alerts on threshold breaches.

How it looks

Validated, typed, production-ready

Zod schemas validate input, generate types, and document your API — all from one source of truth.

// Type-safe Fastify route with Zod validation
import { z } from "zod";

const CreateOrderSchema = z.object({
  items: z.array(z.object({
    productId: z.string().uuid(),
    quantity: z.number().int().positive(),
  })),
});

app.post("/orders", async (req, reply) => {
  const body = CreateOrderSchema.parse(req.body);
  const order = await orderService.create(body);
  return reply.status(201).send(order);
});
FAQ

Common questions.

Express, Fastify, NestJS, or Hono — which framework?

Fastify for high-performance APIs (2x Express throughput). NestJS for large teams that want Angular-style DI and structure. Hono for edge deployments and Cloudflare Workers. Express only for brownfield projects that already use it.

Is Node.js performant enough for our scale?

Node.js handles I/O-bound workloads exceptionally well. For CPU-intensive tasks, we use Worker Threads or offload to dedicated services. Companies like Netflix, LinkedIn, and PayPal run Node.js at enormous scale — the key is architecture, not runtime choice.

How do you handle database access?

Prisma for type-safe ORM with excellent DX. Drizzle for performance-critical queries where you need SQL control. Knex for raw query building. We always use connection pooling, read replicas, and query optimization as part of the baseline.

What about microservices vs. monolith?

We start with a modular monolith (domain-separated modules in one deployable) and extract services only when there's a concrete scaling or team-ownership reason. This avoids premature complexity while keeping the door open for future decomposition.
