Node.js backend development for APIs that scale.
Senior Node.js engineers shipping NestJS, Fastify, TypeScript, PostgreSQL and Redis — APIs, microservices and real-time systems built for production.
The runtime that powers modern web backends.
Node.js is the most widely deployed backend runtime on the modern web — used by Netflix, LinkedIn, Uber, PayPal and Walmart for everything from API gateways to real-time messaging. Arventra Technologies provides Node.js backend development services for teams that need APIs which are fast, typed, observable and built to outlast their first growth spike. We default to TypeScript on every project, use NestJS for structured enterprise APIs, Fastify for high-throughput services, and Hono when the deployment target is the edge.
Our Node.js work spans REST and GraphQL APIs, event-driven microservices on Kafka and RabbitMQ, real-time WebSocket systems, background workers with BullMQ, and full integrations with PostgreSQL via Prisma or Drizzle. Every service ships with OpenAPI specs, Zod validation at the boundary, structured logging, OpenTelemetry tracing, and CI/CD pipelines that deploy to AWS, Cloudflare Workers or your existing Kubernetes cluster. No callback hell, no untyped Express middleware spaghetti, no production surprises.
Node.js capabilities we deliver
REST & GraphQL APIs
OpenAPI-specced REST with NestJS or Fastify, GraphQL with Apollo or Pothos — typed end-to-end with Zod and TypeScript.
Microservices & Monoliths
We pick the right architecture for your stage — modular monoliths for early-stage products, microservices when team and traffic justify the operational cost.
PostgreSQL, Redis, Mongo
Prisma or Drizzle ORMs, Redis for caching and queues, MongoDB when document modeling genuinely fits — never as a default.
Real-time & Streaming
WebSockets with Socket.IO, SSE for one-way streams, Kafka and RabbitMQ for event-driven systems handling millions of messages per day.
Auth, Security & Compliance
JWT, OAuth 2.0, RBAC, rate limiting, OWASP Top 10 mitigations, and audit logging for SOC 2 and ISO 27001 readiness.
DevOps & Observability
Docker, Kubernetes, GitHub Actions CI/CD, deploys to AWS, GCP, Cloudflare Workers, with OpenTelemetry tracing and structured logging.
Typed, observable, production-grade Node.js.
