Node.js development for real-time, high-concurrency systems
Whether it’s a chat platform handling thousands of simultaneous connections or an API layer stitching together your microservices, Dreams Technologies builds production-grade Node.js backends that hold up under real traffic. Headquartered in London with a world-class engineering team in India, delivering for clients across the UK, US, Europe, the Middle East, and Asia for over a decade.
What we build
Node.js solutions we deliver.
Node.js sits alongside our PHP, Python, and .NET backend practices as a core, actively maintained service — not a one-off capability we build up for your project.
Expert Team & Proven Experience
10+ years in the industry, with 500+ happy clients worldwide.
Real-Time Applications & Live Communication
Node’s event-driven, non-blocking I/O model is built for this. We develop chat platforms, live notification systems, collaborative editing tools, and live dashboards using Socket.IO, WebSockets, and Server-Sent Events — so an action on one screen shows up everywhere else instantly.
Microservices & API Backends
We design REST and GraphQL backends using Express, Fastify, or NestJS — chosen on throughput needs, team size, and TypeScript fluency, not a default habit. Each service is independently deployable, observable, and built to scale horizontally.
High-Concurrency, Event-Driven Systems
For workloads with thousands of simultaneous connections — IoT telemetry, live trading feeds, multiplayer backends — we architect around Node’s event loop, using worker threads and clustering to keep latency low under sustained load.
SaaS & Multi-Tenant Platforms
We’ve built and shipped our own commercial products on this stack, including DreamsPOS and DreamsChat — bringing proven multi-tenant data isolation, billing integration, and role-based access patterns to every client SaaS build.
Legacy System Modernization with Node.js
Most legacy monoliths — older PHP, classic .NET, aging Java — don’t need a full rewrite, just a modern integration layer. We wrap existing systems with Node.js API gateways so you modernize incrementally, not in one risky leap.
Streaming & Data-Intensive Applications
Using Node’s native Stream API, we build applications that process and deliver data on the fly — video/audio delivery, large file processing, log and analytics pipelines — without loading everything into memory first.
Our approach
A decade of Node.js delivery, led from the UK
Building and shipping complex software since 2013, across 500+ clients in the UK, US, Europe, Japan, the Middle East, and Asia — we’ve already fixed most of the classic Node.js production issues before they cost you time and money. Our London team manages everything client-facing, from discovery through delivery sign-off, while our engineering team in India handles the deep technical build: senior oversight without the cost of a fully Western dev team.

Choosing a framework
Express, Fastify, or NestJS — based on your project, not habit
We don’t reach for Express by default just because it’s familiar. We select Express for flexibility and the largest talent pool, Fastify when raw throughput is the priority, and NestJS when you need enterprise-grade structure for a larger team — decided upfront, not retrofitted later. And we take over existing Node.js codebases just as often as we start new ones, auditing dependencies and identifying technical debt before modernizing incrementally rather than recommending an unnecessary rewrite.
Start a project
Governance & process
Compliance, cloud infrastructure, and a clear delivery process
GDPR, HIPAA, and SOC 2 controls — encryption in transit and at rest, role-based access control, audit logging, and regular vulnerability assessments using npm audit and Snyk — are designed in from the first architecture decision, not patched in later. The backend behind your app is built by an AWS and Microsoft Azure certified partner, giving direct platform support and deep cloud expertise on every deployment. We start with 1–2 weeks of discovery and architecture planning, move into 1–3 weeks of prototyping and technical validation, build in continuous sprints with weekly progress reports, and follow every launch with 90 days of active support covering monitoring, bug fixes, and performance tuning.

FAQ
Frequently asked questions
What we hear most often about Node.js projects — framework choice, codebase takeovers, security, and what happens after launch.
What kinds of Node.js projects do you take on?
Real-time applications, API and microservices backends, SaaS platforms, legacy modernization, and high-concurrency systems like IoT and streaming platforms. Our experience spans retail, healthcare, hospitality, and service-based businesses.
Is Node.js the right fit for our project, or would another stack work better?
It depends on the workload. Node.js excels at I/O-heavy, real-time, and high-concurrency systems. For CPU-heavy processing, we’ll tell you honestly if another stack — or a hybrid approach — is the better fit.
Which Node.js framework will you use for our project?
We choose based on your needs: Express for flexibility and the largest talent pool, Fastify when raw throughput is the priority, and NestJS when you need enterprise-grade structure for a larger team.
Can you work with our existing Node.js codebase, or only build from scratch?
Both. We regularly take over existing Node.js codebases — auditing dependencies, identifying technical debt, and modernizing incrementally rather than recommending an unnecessary rewrite.
How do you handle security and compliance in Node.js applications?
We build with GDPR, HIPAA, and SOC 2 controls in mind from the start, including encryption in transit and at rest, role-based access control, audit logging, and regular dependency audits using tools like npm audit and Snyk.
What happens after the application is launched?
We include 90 days of post-launch support covering monitoring, bug fixes, and performance tuning. After that, we offer optional retainers for feature development and Node.js version upgrades.
Ready to build a Node.js backend that scales?
If you have a system in mind — or just a performance problem you need solved — start with a conversation. We’ll tell you what’s feasible, what it will take, and which framework actually fits.
