Node.js Development for Real-Time and High-Concurrency Systems
One event loop, thousands of open connections, no drama.
Node.js is the right tool when a system has to hold many connections open at once and push data the moment it changes. Live order tracking, chat, notifications, collaborative editing, IoT telemetry, GPS feeds from a vehicle fleet — these are workloads where a traditional request-response stack starts fighting you and Node simply does not.
It is also a practical choice for API gateways and microservices where the work is mostly moving JSON between services. I build Node backends with an explicit structure rather than one enormous file: layered modules, validated inputs at the boundary, proper error handling, and observability so you can find out why something broke at two in the morning without guessing.
What is included
REST and GraphQL APIs
Fast, documented APIs on Express or NestJS with authentication, rate limiting and versioning built in.
Real-time features
Socket.io and WebSocket systems for live chat, notifications, dashboards and location tracking.
Microservices architecture
Independently deployable services with message queues, service discovery and centralised logging.
Backend for mobile apps
A single API layer serving your Android, iOS and web clients with consistent behaviour and shared authentication.
Automation and integration services
Scheduled jobs, data pipelines, webhook processors and connectors between systems that were never meant to talk.
Performance and scaling
Clustering, caching, connection pooling and profiling to remove the bottleneck rather than throwing servers at it.
Why it is worth doing properly
- Handles thousands of simultaneous connections on modest hardware
- Same language on the server and in the browser, so context switching drops
- The npm ecosystem covers nearly every integration you will need
- Natural fit for streaming, push notifications and live dashboards
Technology used
Chosen to suit the project and your team, not to pad an invoice.
From first call to launch
The same seven steps on every project, so you always know what happens next.
Discovery call
A straight conversation about what the business does, what is not working and what success looks like. No slide deck. If I am not the right fit for the project, I will say so here rather than three weeks in.
45-60 minutesWritten scope and fixed quote
You get a document listing exactly what will be built, what is excluded, the timeline in milestones and a fixed price. Nothing starts until you have read it and agreed. The scope is yours to keep either way.
2-4 daysDesign you can click
Wireframes first for structure, then visual design. For websites you approve a working page in the browser rather than a flat image, so what you sign off is genuinely what gets built.
1-2 weeksBuild in visible milestones
Development runs in two-week milestones on a staging URL you can open any time. You see progress as it happens instead of receiving a status report about work you cannot verify.
2-16 weeksTesting and your review
Cross-browser and mobile testing, speed and security checks, and a review round where your team uses the system properly and lists what needs changing before launch.
3-7 daysLaunch and handover
Deployment, analytics and Search Console setup, a walkthrough recording for your team, documentation, and full credentials handed over. You own everything, including the source code.
1-2 daysSupport after launch
A warranty period covering any bugs at no charge, then an optional maintenance plan for updates, backups, monitoring and new features. No lock-in either way.
