High-performance Node.js backends, REST APIs, GraphQL services, and real-time applications — built by experienced backend engineers based in Delhi. Scalable from day one.
From simple REST APIs to complex real-time platforms — complete Node.js backend development by a single Delhi team.
Clean, documented REST APIs with Express or Fastify. JWT authentication, role-based access control, rate limiting, and OpenAPI/Swagger docs included.
Type-safe GraphQL APIs with Apollo Server or Mercurius. Subscriptions, dataloaders for N+1 prevention, and schema-first design with codegen.
Live chat, notifications, collaborative tools, and live dashboards with Socket.io and Redis pub/sub — handling thousands of concurrent connections.
Node.js microservices with message queues (RabbitMQ, Kafka, BullMQ). API gateway pattern with rate limiting, circuit breakers, and distributed tracing.
Node.js API gateway for LLM integrations — streaming OpenAI/Claude responses, RAG-pipeline calls to Python backends, and AI result caching.
AWS Lambda functions, Cloudflare Workers, and Vercel Edge Functions in Node.js. Pay-per-request, zero-maintenance, infinitely scalable backends.
We pick the right Node.js tools for each project — Fastify over Express when performance is critical, BullMQ for job queues, Prisma for type-safe database access.

DockerAWS EC2/LambdaNginxPM2GitHub ActionsWe use Fastify (3× faster than Express) for high-throughput APIs, async/await throughout, and database query optimization with EXPLAIN ANALYZE on every slow query.
Helmet.js, CORS, rate limiting, input validation with Zod/Joi, SQL injection prevention via parameterized queries — OWASP Top 10 addressed before your API goes live.
Every API we build ships with Swagger/OpenAPI documentation generated from the code. Your frontend team can integrate without needing to ask questions.
Our backend engineers are in Shakurpur, Delhi. Meet us in person, review API contracts on a whiteboard, and avoid offshore timezone and communication issues.
Same team builds your React/Next.js frontend. The Node.js backend and React frontend are designed together — no mismatch between what the API returns and what the UI expects.
We set up structured logging (Winston/Pino), error tracking (Sentry), and APM metrics so you know exactly what your Node.js backend is doing in production.
