Node.js Backend DevelopmentScalable APIs & Microservices

A: Node.js backend cost depends on the API surface (number of endpoints), authentication and authorization requirements, database design, real-time features, and third-party integrations; microservices platforms are scoped as multi-phase programs. You get a fixed quote after a free consultation and the API design phase, scoped endpoint by endpoint — no obligation.

A: A Basic API ships in 4-5 weeks and an Advanced backend in 6-8 weeks, including load testing and documentation. Microservices architectures typically run 3-6 months delivered incrementally. The API specification is agreed in week one, so your frontend or mobile team can start building against it immediately.

A: For I/O-heavy workloads — APIs, real-time systems, microservices — Node.js typically matches or beats Java throughput with a smaller team and faster iteration; Java retains an edge for CPU-bound processing and shops standardized on the JVM. Netflix, LinkedIn, and PayPal all moved major services to Node. With deep Node.js experience, we will tell you honestly when it is the wrong tool — heavy computation belongs in worker services or another runtime.

A: Yes — our founder scaled LiveHindustan.com (HT Media) from crashing at 5M to 60M+ monthly users on a Node-centered stack, and our production APIs serve 10M+ requests/day at sub-50ms response times. The pattern is standard: clustering, Redis caching, connection pooling, horizontal scaling, and load testing before launch rather than after the outage.

A: NestJS for anything a team will maintain long-term: its TypeScript-first modules, dependency injection, and testing story keep large backends coherent — we have used it in production for years. Express still wins for small services and lean serverless functions. We work in both and choose per service, not per fashion.

A: Both. REST is the default for public APIs and straightforward CRUD; GraphQL earns its complexity when many clients (web, mobile, partners) need different slices of the same data. We frequently run a hybrid — REST for webhooks and integrations, GraphQL for the product frontend — with Swagger/OpenAPI or a GraphQL schema as the contract either way.

A: A complete API specification: endpoints, data models, authentication flow, and error conventions, produced in the first week and reviewed by our principal architect. This contract lets frontend and mobile teams build in parallel and gives you a fixed scope to hold us to.

A: JWT or OAuth 2.0 authentication, rate limiting, input validation on every endpoint, parameterized queries against injection, strict CORS, and encrypted secrets management. We follow the OWASP API Security Top 10 and run security review as part of the pre-launch architect sign-off, not as an optional add-on.

A: PostgreSQL is our default for anything with relational data, transactions, or reporting — which is most business applications. MongoDB fits genuinely document-shaped data and rapid schema evolution, and Redis sits alongside either for caching and queues. We run all three in production daily and will justify the choice against your data model, not a trend.

A: Start with a well-modularized monolith unless you have proven scale or independent team boundaries — premature microservices multiply DevOps cost without benefit. We structure monoliths so individual modules can be extracted into services later, and we have performed monolith-to-microservices migrations with zero downtime when clients hit that point.

A: Senior Node.js engineers (the practice is built on years of Node.js and NestJS experience) plus a QA engineer, headquartered in New Delhi and working remote-first. Every backend is architect-reviewed before shipping under our Guardian model by founder Deepak Kumar Jha, Technical Lead.

A: We overlap daily with US EST/PST, UK GMT, EU CET, and UAE GST hours and integrate into your workflow — your GitHub, your CI, your Slack, PR reviews both directions. Backend clients across the US, UK, Europe, and Dubai treat us as an extension of their team rather than a black-box vendor.

A: You own 100% of it — application code, database schemas, Dockerfiles, and CI/CD pipelines all live in your repositories and your cloud accounts from day one. We sign an NDA as standard, and there is no proprietary framework or license tying you to us.

A: Tiers include 30-90 days of support, then most clients keep a monthly retainer covering monitoring response, Node/dependency security patches, performance tuning, and scaling as traffic grows. Documentation ships with the project — endpoint reference, Postman collections, and runbooks — so your own team can operate it if you prefer.
