Node.js Development_
>> Node.js backends that hold up under real traffic: REST and GraphQL APIs, WebSockets, queues, and event-driven services. We pair Node with React or React Native when you want one TypeScript organization across web and mobile.
Projects
Shipped since 2012 across SaaS and product teams
Senior engineers
No juniors on your critical path
Ready
Observability, rate limits, and ownership from day one
Direct answer
Choose Node.js when APIs, real-time features, and TypeScript across web and mobile share one critical path. We ship production backends with senior ownership only: no bait-and-switch, observability from day one. 360+ projects since 2012.

>> When this stack fits
Honest fit gates. We will tell you when another approach is better.
Strong fit
- B2B or B2C SaaS APIs that must scale with product usage
- Real-time features: chat, collaboration, notifications, live dashboards
- TypeScript monorepos shared with React or React Native clients
- Event-driven services, queues, and background workers on AWS
Weak fit
- CPU-bound heavy compute where a different runtime is clearly better
- Staffing requests that expect juniors billed as seniors
- Greenfield work with no product owner and no decision rights

What we deliver
_> Capabilities on this stack
Production APIs
Versioned REST and GraphQL APIs with auth, tenancy, idempotency, and clear ownership boundaries.
Real-time systems
WebSockets and event pipelines for live product experiences that stay stable under load.
SaaS backend patterns
Multi-tenant data isolation, billing webhooks, and admin tooling that procurement can trust.
Observability by default
Logging, tracing, rate limits, and failure modes designed before launch, not after incidents.
How we deliver Node.js work
Fit and architecture
Confirm Node is the right runtime, map domains, and lock non-negotiables: auth, data classes, SLAs.
Thin vertical slice
Ship one production path end to end: API, tests, deploy, and observability before expanding scope.
Harden and scale
Add queues, caching, and failure handling. Document ownership so your team can continue without us.
