Node.js Development Services
We build Node.js back ends, REST APIs and real-time services with Express, plus the integrations and jobs behind them.
What we build with Node.js
REST APIs
APIs for web and mobile apps, with authentication, validation and documentation.
Real-time services
Chat, notifications and live dashboards over WebSockets.
Integrations
Connections to CRMs, payment providers, messaging services and Google APIs.
Background jobs
Queues, webhooks and scheduled jobs that run reliably.
LLM back ends
Streaming responses from OpenAI and Claude models, with usage limits and logging.
Serverless functions
Event-driven functions, often with our AWS development services.
How we secure and scale Node.js APIs
Every Node.js service we ship starts from the same checklist.
Validated input
Every input is checked, and errors are consistent and safe.
Least privilege
Short-lived tokens, permission checks on every route and no secrets in code.
Stateless services
Services scale out behind a load balancer as traffic grows.
Monitoring
Logs, metrics and alerts surface problems before users report them.

Node.js development FAQs
Is Node.js good for real-time apps like chat?
Yes. Node.js keeps thousands of connections open without a thread per user, which suits chat, notifications and live dashboards. The customer support chat MVP we built runs on Node.js and Express.
Should we use Node.js or Python for our back end?
Node.js for APIs, real-time features and teams that already write JavaScript. Python when the work centers on AI or data. Many products use both: a Node.js API in front and Python services behind it.
Can I hire Node.js developers by the month?
Yes. Node.js developers can join your team through staff augmentation for as long as you need them, or we can run a dedicated team that owns the back end with you.
