SaaS backends & APIs.
Built with Node.js.
Node.js is our primary backend for API-driven applications. High-concurrency SaaS platforms, real-time features, microservices — we've built Node.js backends handling thousands of simultaneous connections for clients in the US, UK, and Australia.
Node.js for high-concurrency, API-first applications
Node's event-driven architecture handles thousands of simultaneous connections efficiently. For SaaS backends and real-time features, that concurrency model matters from day one.
SaaS Platform Backends
Multi-tenant backends with subscription billing, team management, and API layers. Node.js handles concurrent users efficiently — we've built SaaS platforms serving hundreds of company accounts.
REST API Development
High-performance APIs connecting frontends, mobile apps, and third-party services. Documented, versioned, and built to survive your first 10,000 users without a rewrite.
Real-Time Applications
Live dashboards, notifications, chat, and collaboration features via WebSockets and Socket.io. Node's event-driven model makes real-time efficient at any scale.
Microservices
Independently deployable services replacing monolithic architectures. We've migrated legacy systems to microservices and built greenfield architectures for enterprise clients.
Not every project needs Node.js. Here's when it's the right call.
Node excels at I/O-bound, high-concurrency workloads. For CPU-heavy computation it's not the best choice — but for most SaaS backends and API layers, it's hard to beat.
Concurrency without the overhead
Node handles thousands of simultaneous connections on a single thread. For SaaS platforms expecting rapid growth, this concurrency model matters from the first day in production.
JavaScript across the full stack
When your frontend is React or Angular, Node on the backend means one language across the stack. Shared validation logic, less context-switching, unified tooling.
npm has 2 million packages
Authentication, payments, PDF generation, email, queuing — there's a battle-tested package. We don't reinvent wheels. We pick the right one and integrate it properly.
TypeScript as standard
We default to TypeScript on all Node projects. Typed APIs, typed database queries, typed middleware — bugs caught at compile time, not at 2am in production.
What we pair with Node.js
Node.js rarely runs in isolation. Here's the full stack we build around it.
Common questions about Node.js development
Do you use TypeScript with Node.js?
Yes — TypeScript is our default. Typed code catches errors at development time rather than runtime, makes refactoring safe, and is the standard for professional Node.js work at any scale.
Express or NestJS — which do you use?
Depends on the project. Express for APIs where you want full control and minimal overhead. NestJS for larger applications where opinionated structure helps — it brings Angular-style architecture to Node. We'll recommend the right one for your use case.
Can you migrate an existing application to Node.js?
Yes. We've migrated PHP, Python, and .NET backends to Node.js. Before recommending migration, we assess whether it's actually the right move — sometimes optimising the existing stack is better value.
How long does a Node.js SaaS project take?
A focused SaaS MVP backend: 12–20 weeks depending on integration complexity. A full-featured platform with complex business logic and third-party integrations: 20–32 weeks. We scope every project individually.
Need a Node.js team for your backend?
We've been building with Node since 2017.
