A cleaner way to hire Node.js developers

Krapton helps you hire Node.js developers who understand what the runtime is good at and where it struggles. Node.js excels at I/O-heavy work: REST and GraphQL APIs, WebSocket servers, webhook processors, BFF layers for React or mobile...

  • An event loop that stays free

    Many Node.js latency problems come from synchronous work hiding in request handlers: synchronous crypto, regex backtracking, giant JSON.stringify calls. A senior developer finds them with --cpu-prof, 0x flame graphs or the Chrome DevTools inspector, then moves the work off the main thread or out of the request path.

  • Background jobs done properly

    Emails, exports, webhooks and AI calls do not belong in the HTTP request. Node.js engineers move them to BullMQ on Redis or to Amazon SQS, with idempotent handlers, retries with backoff, dead-letter handling and dashboards that show stuck or failing jobs.

  • Supply-chain and runtime security

    The npm ecosystem is a frequent attack target. Krapton developers pin dependencies with lockfiles, review install scripts, run npm audit in CI, validate every request body with a schema, and consider the Node.js permission model for processes that should not touch the file system.

  • One language across the stack

    A Node.js developer who also writes TypeScript and React can share validation schemas, types and utilities between frontend and backend, which shortens handoffs. They still respect the boundary: server code stays out of client bundles, and secrets never reach the browser.

Why Node.js?

What makes Node.js the right choice for modern engineering teams.

  • Event-driven architecture

    Node.js utilizes an event-driven architecture, allowing asynchronous handling of I/O operations for improved performance.

  • Non-blocking I/O

    Node.js employs non-blocking I/O operations, ensuring efficient handling of concurrent connections and requests.

  • Scalability

    Node.js is designed for scalability, making it suitable for building applications that require handling a large number of concurrent connections.

  • NPM ecosystem

    Node.js has a rich ecosystem of packages and modules through the Node Package Manager (NPM), facilitating code reuse and project development.

  • Real-time applications

    Node.js is well-suited for building real-time applications such as chat applications, online gaming, and collaborative tools.

  • Microservices architecture

    Node.js is commonly used in microservices architecture, allowing developers to build modular and scalable systems.

What you can build with Node.js

  • REST and GraphQL APIs

    Fastify, NestJS or Express services with schema-validated routes, OpenAPI documentation, cursor pagination, rate limiting and structured logging with Pino, deployed as containers or serverless functions.

  • Real-time messaging servers

    Chat, notifications and live collaboration backends using Socket.IO or the ws library, with Redis pub/sub or a Socket.IO adapter so messages reach clients on every instance behind a load balancer.

  • Webhook and integration hubs

    Services that receive Stripe, Shopify or CRM webhooks, verify signatures, store events idempotently, and fan work out to queues so a slow downstream system never causes missed or duplicated events.

  • Backend for frontend layers

    BFF services that aggregate several internal APIs into screen-shaped responses for web and mobile clients, cache with Redis, and shield the frontend from changes in legacy systems.

  • LLM and streaming endpoints

    APIs that call OpenAI or Anthropic models, stream tokens to the browser over server-sent events, enforce timeouts and token budgets, and log prompts and costs for later review.

  • Queue workers and schedulers

    Background processors built on BullMQ or cloud queues for exports, emails, data syncs and scheduled jobs, with concurrency limits, graceful shutdown on SIGTERM and visibility into failed jobs.

Running Node.js services that stay fast

Node.js performance problems rarely show up in development, where one user and a small dataset never stress the event loop. In production the symptoms are rising p99 latency, health checks timing out under load and containers restarting with heap errors. A senior Node.js developer instruments before guessing: monitorEventLoopDelay from perf_hooks or an APM agent shows whether the loop is blocked, OpenTelemetry traces show which downstream call is slow, and heap snapshots taken minutes apart reveal what keeps growing. The fixes are usually specific rather than architectural, such as replacing a synchronous library call, bounding an in-memory cache with an LRU, raising a database pool size to match concurrency, or streaming a large response instead of building it in memory. Each fix is verified with a load test using autocannon or k6 before release.

Operational discipline matters just as much. Krapton engineers implement graceful shutdown so a SIGTERM from Kubernetes or a platform redeploy drains in-flight requests and closes database and queue connections cleanly. They set explicit timeouts on every outbound HTTP call, because a hanging dependency otherwise ties up sockets until the process degrades. They decide on ESM versus CommonJS per project and stay consistent, keep the runtime on an LTS line with a planned upgrade before end of life, and use Dependabot or Renovate so dependency updates arrive in small, reviewable pull requests. Configuration comes from validated environment variables, secrets come from a manager such as AWS Secrets Manager or Doppler, and nothing sensitive ends up in logs. The result is a service your own team can operate confidently.

Node.js in action

const express = require('express');
        const axios = require('axios');
        
        const app = express();
        const PORT = 3000;
        
        // Middleware to parse JSON
        app.use(express.json());
        
        // Middleware for handling errors
        app.use((err, req, res, next) => {
          console.error(err.stack);
          res.status(500).send('Something went wrong!');
        });
        
        // Express route to fetch data from an external API
        app.get('/api/data', async (req, res, next) => {
          try {
            // Simulate asynchronous operation (e.g., fetching data from an external API)
            const externalApiResponse = await axios.get('https://jsonplaceholder.typicode.com/todos/1');
            
            // Extract relevant data from the external API response
            const responseData = {
              id: externalApiResponse.data.id,
              title: externalApiResponse.data.title,
            };
        
            // Send the formatted data as JSON to the client
            res.json(responseData);
          } catch (error) {
            // Pass the error to the error-handling middleware
            next(error);
          }
        });
        
        // Express route to handle other routes
        app.get('/', (req, res) => {
          res.send('Hello, this is a Node.js application!');
        });
        
        // Start the Express server
        app.listen(PORT, () => {
          console.log(Server is running);
        });

What our Node.js developers know

Every Krapton developer is vetted with real production experience in Node.js across multiple industry domains.

  • Node.js development proficiencyExpertise in server-side development using Node.js for building scalable applications.
  • Event-driven programmingMastery of event-driven programming concepts in Node.js for handling asynchronous operations.
  • Non-blocking I/O implementationSkills in implementing non-blocking I/O operations in Node.js for efficient handling of concurrent requests.
  • NPM package managementProficient in using and managing packages through the Node Package Manager for project development.
  • Real-time application developmentExperience in developing real-time applications using Node.js for interactive and dynamic functionalities.
  • Microservices architecture practicesAbility to design and implement microservices architecture using Node.js for modular and scalable systems.

What our Node.js developers go deep on

  • Event loop and async internals

    Understanding microtasks versus macrotasks, libuv’s thread pool and UV_THREADPOOL_SIZE, AbortController for cancellation, and how unhandled promise rejections and blocking calls affect every request on a process.

  • Streams and backpressure

    Processing large files, CSV imports and HTTP uploads with stream.pipeline, respecting backpressure so memory stays flat, and using async iterators or Web Streams where they simplify the code.

  • Frameworks and API design

    Building with Fastify plugins and JSON Schema validation, NestJS modules, guards and interceptors, or Express middleware, and designing versioned REST or GraphQL contracts that clients can rely on.

  • Data access and pooling

    Using Prisma, Drizzle or Kysely with PostgreSQL, sizing connection pools for containers and serverless, avoiding N+1 queries, and managing transactions and migrations safely across deployments.

  • Observability in production

    Structured logs with Pino, OpenTelemetry traces and metrics, event-loop delay and heap monitoring, and alerts tied to latency and error budgets rather than raw CPU graphs.

  • Testing and runtime tooling

    Writing tests with the built-in node:test runner, Vitest or Jest, using Supertest or Fastify’s inject for HTTP tests, Testcontainers for real databases, and running TypeScript through tsx or native type stripping.

Common Node.js projects we deliver

  • Diagnosing p99 latency spikes in production

    Slow tail requests often come from event-loop blocking, connection pool exhaustion or garbage collection pauses. The developer correlates event-loop delay metrics with traces from OpenTelemetry, captures CPU and heap profiles, and fixes the specific hot path.

  • Upgrading from an end-of-life Node.js version

    Old runtimes stop receiving security patches. The engineer moves to a current LTS release, replaces deprecated APIs, updates native modules that need rebuilding, checks ESM and CommonJS interop, and runs the test suite on both versions before switching production.

  • Splitting a growing Express monolith

    Large Express apps drift into tangled middleware and shared globals. The developer introduces module boundaries, typed service layers and dependency injection, sometimes adopting NestJS, and extracts only the parts that truly need independent scaling into separate services.

  • Fixing memory leaks in long-running services

    Containers restarting with out-of-memory errors usually point to unbounded caches, listeners never removed or closures holding request data. The engineer compares heap snapshots under load, fixes the retaining path, and aligns container memory limits with --max-old-space-size.

Node.js solutions by industry

  • Fintech

    Payment webhooks, ledger APIs and notification services where idempotency keys, strict input validation and audit logging matter more than raw throughput.

  • Media and streaming

    Chat, live comments and presence features with many concurrent connections, a natural fit for Node.js’s non-blocking I/O when CPU-heavy transcoding runs elsewhere.

  • Logistics

    Tracking APIs, carrier integrations and webhook processing that juggle many external services, where queues and retries absorb slow or unreliable partner endpoints.

  • SaaS platforms

    Multi-tenant APIs, billing integrations and background jobs written in TypeScript, sharing types and validation with the React frontend for faster, safer feature work.

Node.js vs Go

Node.js and Go both build fast network services, but they suit different teams and workloads. Node.js shares a language with the frontend and has the largest package ecosystem, which speeds up product work. Go compiles to a single binary, uses all CPU cores through goroutines, and handles CPU-bound or very high-concurrency services with less tuning. Many teams run both.

Hiring Node.js developers — answered

Practical answers to the questions CTOs and founders ask us most often before they hire.

How quickly can I hire a Node.js developer from Krapton?

Within 24 hours of the initial call. We keep a bench of pre-vetted Node.js engineers, so once you confirm the brief we line up two or three shortlisted CVs within a business day and can onboard the selected developer within two.

How much does it cost to hire a dedicated Node.js developer from India?

Blended hourly rates for senior Node.js engineers typically fall in the $22–$45 USD range depending on seniority and engagement length. Dedicated developers are billed monthly with no lock-in.

Are your Node.js developers full-time employees or freelancers?

Every Node.js developer you hire through Krapton is a full-time, in-house engineer — we never subcontract to freelancers or agencies. That means consistent code quality, signed NDAs, and a single point of accountability for your project.

Who owns the code and IP my Node.js developers write?

You do — 100%. IP assignment and confidentiality are covered by the contract and a free NDA on request. All code lives in your repositories, on your infrastructure, under your accounts from day one.

What should a senior engineer know when I hire Node.js developers?

They should explain the event loop, not just use async and await. Expect clear answers on what blocks the loop, how libuv’s thread pool handles file system and crypto work, how backpressure works in streams, and how to shut down gracefully. Ask them to profile a slow endpoint with --cpu-prof or the inspector and to explain how they would size a database connection pool.

Should we choose Express, Fastify or NestJS?

Choose based on team size and existing code rather than benchmarks alone. Fastify suits new, performance-sensitive APIs with schema validation built in. NestJS adds modules, dependency injection and conventions that help larger teams, and it can run on Fastify underneath. Express remains reasonable for existing codebases, and Express 5 improved async error handling, so a rewrite is rarely justified on its own.

Should we move from Node.js to Bun or Deno?

Usually not for an existing production service. Bun and Deno offer fast startup, built-in tooling and good Node.js compatibility, and they are worth evaluating for new scripts, tests or edge workloads. For established services, Node.js still has the broadest library support, APM coverage and hosting options. If you experiment, run your real test suite and a load test first, since compatibility gaps tend to appear in native modules.

How do Node.js developers secure an API?

By validating every input and limiting what the process can reach. That means schema validation with Zod, TypeBox or JSON Schema on each route, parameterized queries, helmet-style security headers, rate limiting, and short-lived tokens checked on every request. On the supply-chain side it means lockfiles, npm audit in CI, careful review of install scripts and new dependencies, and secrets loaded from a manager instead of committed files.

How often should we upgrade Node.js versions?

Plan an upgrade at least once a year, moving between LTS releases well before the current one reaches end of life. Only LTS lines receive long-term security fixes, so production should never sit on a short-lived Current release. A safe upgrade runs CI on both versions, rebuilds native modules, checks deprecation warnings, and rolls out to one service or canary instance first.
