Node.js Backend Development Services in India
Node.js is our default backend choice when a project needs speed-to-ship, real-time features, or a single language across the stack. We've built Node.js backends for SaaS dashboards, mobile apps, multi-tenant platforms, and real-time collaboration tools — using NestJS, Express, or Fastify depending on what fits the team and scale. TypeScript everywhere, proper testing, observability built in, and deployment automated from day one.
Why teams choose us for Node.js Backend Development
Most Node.js codebases we audit suffer from the same problems: callback hell from a 2018 mindset, no separation between routing and business logic, every controller fetching its own database connection, and zero test coverage. We do it differently. Modern async/await with TypeScript strict mode, repository + service-layer separation, dependency injection where it earns its weight, and integration tests that actually catch regressions. The result: codebases the next developer can pick up cleanly, and APIs that don't fall over at 10x current load.
When Node.js Backend Development is the right choice
Node.js is the right backend when you need real-time features (WebSockets, server-sent events), your team already runs JavaScript/TypeScript on the front-end and a unified language reduces context-switching, you're building a fast MVP that needs to scale later, or you're consuming and aggregating multiple third-party APIs. It's not the right fit for CPU-heavy data processing (use Python or Go), enterprise transactional systems with complex business rules (Java/.NET still win), or when you specifically need PHP's ecosystem (use Laravel).
Our Node.js Backend Development Process
OpenAPI-first or GraphQL schema-first. We design the contract before writing code, so front-end and backend can develop in parallel and integration tests have a fixed target.
NestJS for opinionated structure on larger projects, Express + custom architecture for smaller ones, Fastify when raw performance matters. Postgres or MongoDB. Prisma or Drizzle ORM. Redis for caching and queues. We pick based on the project, not a default we always use.
TypeScript with strict mode and noUncheckedIndexedAccess. Repository pattern where it adds clarity, services for business logic, controllers thin. Validation via Zod or class-validator. Async error boundaries on every route.
Unit tests for service-layer logic, integration tests for API contracts, end-to-end smoke tests for critical paths. Sentry for errors, OpenTelemetry traces, structured JSON logging via Pino. You see exactly what's happening in production.
Docker containers, deployed to Vercel / Railway / Render / Fly.io for most projects, AWS ECS or Kubernetes when scale demands it. CI/CD via GitHub Actions. Database backups automated. Zero-downtime deploys.
What we deliver
- REST API development (Express, Fastify, NestJS)
- GraphQL API development (Apollo Server, Pothos, Yoga)

Frequently asked questions
How much does a Node.js backend cost in India?
Starter APIs (10-30 endpoints, basic auth, Postgres): ₹40k-₹100k. Production backends (GraphQL, real-time, jobs, complex data): ₹100k-₹300k. Multi-service / enterprise: ₹300k+. Cost scales with endpoint count, real-time complexity, and observability requirements.
Should I use NestJS or plain Express?
NestJS for projects expected to grow past 10-15 contributors or 50+ endpoints — its opinionated structure pays back. Plain Express + custom architecture for smaller projects, MVPs, and tight deadlines. We use both regularly and pick per project.
REST or GraphQL?
REST when consumers are first-party (your own front-end, your own mobile app), the data model is simple, and you don't need flexible querying. GraphQL when you have multiple front-ends with different data needs, complex nested relationships, or third-party API consumers. Most of our recent backends are REST — GraphQL is over-applied for projects that don't need it.
Can you build the mobile app backend AND the mobile app?
Yes. We build full-stack — Node.js backend + React Native or Flutter mobile app + admin dashboard. One team, one codebase repository, one PM. Most clients prefer this over splitting backend/mobile across two vendors.
Do you do microservices or monoliths?
Honest answer: monoliths win for ~80% of projects. We only recommend microservices when there's a specific reason — compliance/data isolation, independent scaling needs, or genuine team/codebase size that justifies the operational overhead. Anyone telling early-stage startups to start with microservices is selling complexity.

Other services
We've shipped 7+ Shopify stores for D2C brands, B2B catalogs, and subscription businesses across India, USA, Canada, UK, and UAE. Whether you're launching your first store on Basic Shopify or replatforming a 10,000-SKU catalog onto Shopify Plus, our team handles the full build — strategy, theme development, app integration, payments, shipping, and post-launch growth.
WordPress runs ~43% of the web for a reason — it's the most flexible, well-supported CMS available. We build WordPress sites and WooCommerce stores that load fast, rank well, and stay maintainable past year five. From a 5-page brochure site to a 50,000-SKU WooCommerce catalog, every build follows the same engineering standards: clean code, proper caching, security hardening, and a CMS your content team actually wants to use.
Laravel is the framework we reach for when a project needs more than a CMS but less than a microservices platform — internal tools, B2B SaaS, admin dashboards, custom CRMs, and REST/GraphQL APIs. We've shipped 6+ Laravel projects across healthcare, fintech, logistics, and education, with clean architecture, proper test coverage, and admin panels that ops teams actually enjoy using.
