Node.js
Build scalable server-side applications and APIs with the event-driven JavaScript runtime.
Scalable server-side applications powered by Node.js.
Node.js is the de facto runtime for high-throughput, non-blocking server applications. We use it to ship REST and GraphQL APIs, real-time systems, background workers, and edge functions for enterprise clients.
Our Node.js engineers pair the runtime with TypeScript, Fastify, NestJS, and Prisma to deliver type-safe, production-grade backends with predictable latency and clear operational guarantees.
Benefits
Node.js Development Services
We design, build, and operate Node.js services from prototype to production-grade platforms handling millions of requests per day.
API engineering
REST and GraphQL APIs built with Express, Fastify, and NestJS, fully typed with TypeScript and OpenAPI contracts.
Real-time systems
WebSockets, Server-Sent Events, and pub/sub backends for chat, dashboards, and collaborative apps.
Background processing
Job queues with BullMQ and Redis for emails, webhooks, and long-running tasks with retries and observability.
Edge and serverless
Vercel Functions, AWS Lambda, and Cloudflare Workers for low-latency global delivery.
What we do
Our Node.js Capabilities
We follow strict engineering practices around testing, observability, and security so your services stay healthy in production.
TypeScript-first backends
Strict typing across handlers, services, and data layers to catch bugs at compile time.
Database integration
Prisma, Drizzle, and TypeORM with PostgreSQL, MySQL, and MongoDB, including migrations and seed pipelines.
Authentication and authorization
OAuth, JWT, session management, and role-based access control with audit trails.
Observability
Structured logging, OpenTelemetry tracing, and Prometheus metrics for full production visibility.
Testing
Unit tests with Vitest and Jest, integration tests with Testcontainers, and contract tests for APIs.
Performance tuning
Profiling, clustering, worker threads, and connection pooling to handle peak traffic.
