Hire Expert Node.js Developers — Backend API & Microservices Specialists
Pre-vetted Node.js developers with deep expertise in REST API design, GraphQL, microservices architecture, real-time systems with Socket.io, and cloud deployment on AWS and Azure. Fast, scalable, production-ready backends. Based in Udaipur, India — available in 48 hours.
Node.js is the dominant backend platform for JavaScript-stack applications — powering everything from simple REST APIs to high-throughput microservices handling millions of requests per day. The architecture decisions made when building a Node.js backend — event loop usage, connection pooling, caching strategy, queue design — determine whether your API scales smoothly or collapses under production load. PapaSiddhi Technologies has a team of Node.js backend specialists who have built production APIs at every scale: startup REST APIs serving 1,000 users, SaaS platform APIs handling 100,000 daily active users, and enterprise microservice architectures processing millions of events per day. Based in Udaipur, India, our developers serve clients across the USA, UK, Netherlands, Australia, and UAE — covering Express.js, Fastify, NestJS, GraphQL, Socket.io, Kafka, Redis, PostgreSQL, and MongoDB, deployed on AWS with full Infrastructure as Code. Their expertise costs 50–60% less than equivalent UK or US Node.js backend developers.
Why Choose Us
What Our Node.js Developers Can Do For You
- Design and build production REST APIs with Express.js, Fastify, or NestJS — versioned, documented with OpenAPI/Swagger, and secured
- Implement GraphQL APIs with Apollo Server or Mercurius — schema design, resolvers, DataLoader for N+1 prevention, and real-time subscriptions
- Build real-time systems using Socket.io for live notifications, collaborative features, gaming, and event-driven dashboards
- Design microservice architectures — service decomposition, inter-service communication via REST, gRPC, or message queues (Kafka, RabbitMQ)
- Implement authentication and authorisation — JWT with refresh token rotation, OAuth 2.0, API key management, and role-based access control
- Optimise Node.js API performance — connection pooling, Redis caching, response streaming, worker threads for CPU-bound tasks, and database query optimisation
- Build background job processing systems using Bull/BullMQ — scheduled jobs, retry logic, dead letter queues, and job monitoring dashboards
- Deploy Node.js applications to AWS (Lambda, EC2, ECS) or Azure with Docker, Kubernetes, and Terraform-managed infrastructure
- Integrate third-party APIs — payment gateways, email providers, SMS, cloud storage, and enterprise systems with proper error handling and retry logic
- Write comprehensive backend tests — Jest unit tests, Supertest API integration tests, and contract tests for service boundaries

Why Hire Through PapaSiddhi
Backend Architecture Assessment
Every Node.js developer is evaluated on API design quality, database optimisation, caching strategy, error handling patterns, security implementation, and understanding of async patterns beyond basic callbacks.
Production API Experience
We verify that every developer has built Node.js APIs used in production — with real users, real load, and real incident experience. Tutorial projects and portfolio APIs do not qualify.
48-Hour Start
Pre-vetted Node.js backend developers ready to integrate into your codebase, attend your technical reviews, and ship production-ready API endpoints within the first sprint.
API Security Standards
Our developers implement OWASP API Security Top 10 as standard — authentication on every endpoint, rate limiting, input validation with Zod/Joi, parameterised queries, secrets management, and security header configuration.
Backend Specialist, Not Generalist
A Node.js specialist writes better APIs faster than a generalist who does everything. Our backend developers focus on the API layer — performance, security, reliability, and maintainability — without spreading thin.
API Documentation Standard
Every API endpoint is documented with OpenAPI/Swagger — request schemas, response formats, authentication requirements, and error codes. Frontend developers and API consumers can integrate without back-and-forth.
What You Gain by Hiring With Us
Senior Node.js backend developers in India with NestJS, GraphQL, microservices, and AWS expertise cost 50–60% less than US or UK equivalents — without sacrificing API design quality, performance standards, or TypeScript discipline.
Our Node.js developers design APIs that scale. Properly implemented Node.js with connection pooling, Redis caching, and horizontal scaling handles 10,000+ requests per second on modest infrastructure.
Within 48 hours of your Node.js developer starting, a first API endpoint — properly authenticated, validated, error-handled, and tested — is merged and deployed to your staging environment.
Our backend architects design for 99.9%+ API uptime: health check endpoints, graceful shutdown, circuit breakers for downstream services, retry logic with exponential backoff, and load balancer integration.
Four Steps. 48 Hours to First Commit.
From sharing your requirements to a pre-vetted developer ready to start — faster than any other route.
Describe Your API Needs
Tell us your Node.js framework preference (Express, Fastify, NestJS), database stack, real-time requirements, expected request volume, and whether this is a new API or ongoing development on an existing backend.
Backend Profiles in 24hrs
We present 2–3 pre-vetted Node.js developer profiles — API architecture examples, TypeScript proficiency, database expertise, cloud deployment experience, and verified production scale references.
Technical Interview
Interview candidates with your backend-specific questions. We can arrange live API design challenges, Node.js performance scenario discussions, or database optimisation exercises.
API Delivery Starts
Developer joins your repository, reviews existing API architecture, and delivers the first new endpoint — with authentication, validation, tests, and OpenAPI documentation — within sprint one.
Who Typically Hires Our Node.js Developers
Challenge
The frontend prototype is impressive but the backend is a mess of direct database calls from the React frontend, hardcoded credentials in client-side code, no authentication, and no error handling. The product cannot be shipped to real users in its current state but the team's skills are frontend-heavy.
Outcome
A dedicated Node.js backend developer who designs the proper API layer — authenticated endpoints, data validation, database abstraction with Prisma or Mongoose, proper secrets management, rate limiting, and staging/production environments — allowing the React team to focus on the frontend while the backend developer ensures the API is production-ready.
Challenge
The Node.js API that worked fine at 100 users is showing database connection timeouts, slow endpoint response times, and memory leak symptoms at 10,000 users. The engineering team has added caching in random places and vertical scaled the server three times, but the root cause is poor connection management and missing indexes.
Outcome
A senior Node.js performance specialist who profiles the application, identifies the actual bottlenecks (connection pool exhaustion, missing composite indexes, N+1 query patterns, synchronous operations blocking the event loop), implements proper Redis caching with appropriate TTLs, and redesigns the highest-traffic endpoints for horizontal scalability.
Challenge
A Node.js monolith has grown to 500,000 lines of code. Deployments are risky, modules are tightly coupled, and performance issues in one area affect the entire application. The team has identified 8 bounded contexts that should be independent services, but doesn't have the microservice architecture experience to design the decomposition safely.
Outcome
A Node.js architect who leads the microservice decomposition strategy — identifying service boundaries, designing the event-driven communication layer with Kafka, implementing distributed tracing with OpenTelemetry, designing the API gateway, and executing the strangler fig migration that extracts services incrementally without disrupting the monolith during transition.
