Work with Node.js experts trusted by the world's top tech teams.

We use clustering (Node.js cluster module) for multi-core utilization, PM2 for process management, reverse proxies (Nginx) for load balancing, and optimize the event loop by avoiding blocking operations and using worker threads for CPU-intensive tasks.

We apply a rigorous multi-stage vetting process that evaluates event loop understanding, async patterns (Promises, async/await), streams, error handling, performance optimization, and real-world problem-solving. Less than 1% of applicants make it through.

We can have a fully vetted Node.js engineer ready to start within two weeks of your request, and full teams typically onboard within a month.

Yes — Socket.io (fallback support, rooms, namespaces), raw WebSockets (ws library), uWebSockets for high performance, and Server-Sent Events (SSE) for one-way real-time streams.

Modular architecture with separation of concerns (routes, controllers, services, repositories), dependency injection (TypeDI, Awilix), clean architecture patterns, and monorepos (Nx, Turborepo) for multi-service projects.

Yes — for type safety, better tooling, and maintainability. We use ts-node for development, tsx for fast execution, and compile to JavaScript for production. We also use Zod for runtime validation.

Yes. We incrementally replace endpoints using a strangler pattern with a proxy routing traffic to both old and new systems, or do a complete rewrite with parallel running and traffic shifting.

Bull/BullMQ (Redis-backed) for robust job queues, Agenda (MongoDB-backed) for simpler needs, or RabbitMQ/Kafka for event-driven architectures. We also use worker threads for CPU-intensive background tasks.

We document thoroughly with JSDoc/TSDoc, follow consistent code style (ESLint, Prettier), write comprehensive tests (Jest, Vitest), implement structured logging, and conduct knowledge-transfer sessions.

Jest/Vitest for unit tests, Supertest for API integration tests, Testcontainers for database testing, Pact for contract testing, and Artillery/k6 for load testing.

We have deep experience in finance, healthcare, and e-commerce. Our engineers implement Helmet.js for security headers, express-rate-limit for brute force protection, JWT/OAuth2 for authentication, data encryption, and comply with HIPAA, SOC 2, and PCI-DSS.

Yes. We can provide dedicated QA engineers who specialize in Node.js testing — Jest, Vitest, Supertest, Cypress (E2E), and k6/Artillery for load testing.
