NODE.JS
BACKENDS
THAT SCALE

With Node.js we build fast APIs, event-driven services and integration layers that reliably power Shopware, mobile apps and web frontends.

Stage image

We areNode.jsengineers

We combine modern runtimes with pragmatic architecture: clear modules, observability and automated tests – so your backend stays stable under load.

  • REST & GraphQL APIs, WebSockets and message queues
  • Authentication, rate limits and security best practices
  • Containers, CI/CD and cloud-native operations
  • Monitoring, logging and performance tuning

Event-driven, non-blocking I/O

Node.js's single-threaded event loop handles many concurrent connections efficiently – ideal for APIs, streaming and real-time signals without thread explosion.

JavaScript/TypeScript end-to-end

A unified language between frontend and backend shortens onboarding, simplifies type sharing and reduces context switching in product teams.

V8 & npm ecosystem

The V8 engine delivers heavily optimised JIT performance; millions of npm packages accelerate auth, validation, database clients and observability.

Scaling & microservices

Small, focused services can be deployed and scaled independently – Node.js is a preferred stack for gateways, BFFs and asynchronous workers.

Real-time & high concurrency

Chat, live updates, gaming backends or IoT ingest: WebSockets and streams in Node.js keep latency low when many clients connect at once.

BFF and integration hub

A backend-for-frontend bundles calls to many systems, normalises errors and offloads mobile or web clients – Node.js is excellent as a lean orchestration layer.
