Node.js development
We engineer Node.js services that handle thousands of concurrent connections at once: streaming APIs, real-time collaboration, and event-driven platforms built to scale horizontally from day one.
In short
Node.js, at a glance
- The non-blocking event loop handles huge concurrency on modest hardware, so your infra bill stays small.
- Native streams and an event-driven core make live data, sockets and queues feel effortless.
- JavaScript and TypeScript everywhere means shared models, shared validation and faster teams.
- npm's 2M+ packages mean we rarely reinvent the wheel. We assemble proven parts.
Why Node.js
Node.js in production.
Node.js runs JavaScript on the server with a single-threaded, non-blocking event loop. That makes it exceptional at I/O-heavy workloads: APIs, gateways, streaming, chat and anything that has to talk to a lot of clients at once.
We pair it with TypeScript end-to-end, so the same types flow from your database to your frontend. The result is fewer integration bugs, faster onboarding for new engineers, and a codebase that's a pleasure to refactor as the product grows.
Blazing async I/O

Built for real-time
Native streams and an event-driven core make live data, sockets and queues feel effortless.
One language, full stack
JavaScript and TypeScript everywhere means shared models, shared validation and faster teams.
The largest ecosystem
npm's 2M+ packages mean we rarely reinvent the wheel. We assemble proven parts.
Scales horizontally
Stateless services cluster cleanly behind a load balancer and containerise without drama.
Battle-tested at scale
It powers Netflix, PayPal and LinkedIn, and a huge, active community stands behind it.

Concurrency, not threads
Event-driven backends, real-time systems and APIs that stay fast under load.

How we work
Senior engineers, accountable to outcomes. Every change typed, reviewed and tested.
01Custom web application development
Full-stack products built on Node.js with a typed API layer and a modern frontend, architected for your domain rather than a boilerplate.
- Domain-driven service design
- TypeScript end-to-end
- Test-covered business logic
02API development & integration
REST, GraphQL and gRPC APIs that expose your platform cleanly and connect to the third parties your business runs on.
- OpenAPI / schema-first contracts
- Auth, rate-limiting & versioning
- Payment, CRM & ERP integrations
03Real-time application development
Chat, dashboards, multiplayer and live collaboration powered by WebSockets, SSE and pub/sub backbones.
- WebSocket & Socket.IO
- Presence & sync engines
- Redis / Kafka event pipelines
04Microservices architecture
Decompose the monolith into independently deployable services with clear contracts and resilient messaging.
- Service boundaries & contracts
- Message queues & sagas
- Containerised, observable services
05E-commerce & SaaS platforms
High-throughput commerce backends and multi-tenant SaaS engines with billing, entitlements and analytics.
- Headless commerce APIs
- Usage-based billing
- Multi-tenant data isolation
06Maintenance, support & migration
Modernise legacy Node services, lift them to the current LTS, and keep them healthy with monitoring and SLAs.
- LTS upgrades & hardening
- Performance profiling
- 24/7 monitoring & on-call

Run & ship
How we build it
Architecture built to last.
A Node.js platform we'd ship, layer by layer — built to stay fast as traffic grows.
A look at what we've shipped.

A real-time wealth platform built for scale
Re-architecting a legacy investment portal into a modular, real-time platform that holds up under heavy concurrent load.
View case studyA six-step cycle, repeated until it's right.
Transparent, predictable and collaborative. You always know what's shipping next and why.
Discovery
We map the business, users and constraints, then pressure-test the problem before a line of code.
Planning
Architecture, scope, and a sprint roadmap with clear milestones, budgets and success metrics.
Design
Research-led UX and high-fidelity interfaces, validated with prototypes before build.
Development
Senior-led engineering in two-week sprints with demoable increments and continuous review.
Testing & QA
Automated and manual testing, security review and performance hardening before release.
Launch & Care
Confident deployment, monitoring and SLA-backed support that keeps things humming.
Node.js questions, answered.
Still unsure if Node.js is right for your project? A senior engineer will tell you straight on a free call.
Non-blocking I/O for very high concurrency, a single language across the whole stack, the largest package ecosystem in software (npm), and a mature toolchain that's proven at the scale of Netflix and PayPal.
APIs and microservices, real-time apps (chat, dashboards, collaboration), streaming services, e-commerce and SaaS backends, command-line tools, and serverless functions. It excels wherever I/O, not raw CPU, is the bottleneck.
Every engagement can include SLA-backed monitoring, alerting and on-call, scheduled LTS upgrades, dependency and security patching, and a clear escalation path. You always know who to call and how fast they'll respond.
Yes. With TypeScript, well-defined service boundaries, observability and horizontal scaling, Node.js runs mission-critical systems for some of the largest companies in the world. We architect for that from the first sprint.
It depends on scope, integrations and SLAs. After a free consultation we give you a clear, fixed-scope estimate, and recommend the engagement model (fixed, dedicated team or staff augmentation) that fits your budget and timeline.
