Node.js Development

Build high-performance, real-time, and scalable backend systems with Node.js and modern APIs. Power secure enterprise workloads with fast, resilient, and cloud-ready architectures.

At Radiansys, we build Node.js Back-End Systems that deliver fast APIs and real-time performance. We design scalable microservices and cloud-ready deployments for enterprise workloads.

Build secure REST, GraphQL, and gRPC APIs using Express.js, NestJS, and Fastify.

Design microservices with Docker, Kubernetes, and event-driven communication.

Implement real-time capabilities with WebSockets, Socket.io, and streaming pipelines.

Deploy serverless Node.js workloads on AWS Lambda, Azure Functions, and GCP Cloud Functions.

How We Implement Node.js

At Radiansys, Node.js engineering is handled as a complete back-end lifecycle, not just API development. We architect modular, event-driven systems that combine modern runtime frameworks, distributed microservices, cloud orchestration, and governed deployment pipelines.Every implementation includes performance optimization, API security, RBAC/ABAC controls, CI/CD automation, and compliance aligned with SOC2, GDPR, HIPAA, and ISO 27001.

API Architecture & Node.js Foundations

We design structured back-end architectures using Express.js, NestJS, and Fastify. This includes routing strategies, validation frameworks, service layers, caching, and error-handling patterns tailored to enterprise workflows. Each API is engineered for predictable latency, high throughput, and long-term maintainability across distributed environments.

01

Microservices & Distributed Systems

We convert monolithic backends into independently deployable microservices using Docker, Kubernetes, and event-driven designs. Domain boundaries are defined for teams, features, and services to enable parallel development. This approach reduces deployment risk, improves fault isolation, and supports multi-region scalability without service interruptions.

02

Real-Time Event Processing & Messaging

We architect real-time systems using WebSockets, Socket.io, Redis streams, Kafka, and pub/sub messaging. These pipelines support live interactions, streaming workloads, notifications, and collaborative features that require millisecond responsiveness. Consistent event handling ensures reliable behavior across high-traffic, real-time applications.

03

Serverless Engineering & Cloud-Native Workflows

Node.js workloads are deployed using AWS Lambda, Azure Functions, and GCP Cloud Functions to achieve auto-scaling, rapid execution, and operational efficiency. Serverless architectures handle triggers, cron jobs, and lightweight APIs while integrating securely with cloud-managed services, IAM policies, and event gateways.

04

Performance Optimization, Quality Engineering & Security

We test and optimize every backend module with load testing, clustering, caching strategies, runtime tuning, and advanced monitoring tools. Security includes OAuth2, JWT, encryption, rate limiting, dependency scanning, and secret rotation. Each deployment undergoes regression checks, resilience validation, and performance benchmarking under peak load.

05

CI/CD Pipelines, Observability & Deployment Automation

We build CI/CD pipelines that manage builds, tests, releases, versioning, and environment promotion across distributed services. Automated rollouts ensure stable deployments, rapid updates, and controlled migrations. Logging, metrics dashboards, and observability tools maintain system health across cloud, hybrid, and on-prem infrastructure.

06

Governance, Compliance & Long-Term Maintainability

We enforce coding standards, architectural patterns, documentation, and lifecycle governance across all Node.js services. Audit logging, dependency checks, and policy enforcement ensure compliance with enterprise regulations. This foundation keeps large-scale back-end ecosystems secure, reliable, and future-ready over years of continuous evolution.
