Node.js Backend Teams Built for Scale.
Node.js engineers who build event-driven backends that handle millions of requests without breaking a sweat. From Express and Fastify APIs to real-time WebSocket servers and serverless functions, our developers architect systems for throughput, reliability, and maintainability. We serve backend and platform teams across the United States, Germany, Netherlands, and the UK, with 4–6 hours of daily CET overlap and fully GDPR-compliant infrastructure.
Use Cases
What we build with Node.js.
REST & GraphQL API Development
Production APIs with Fastify, Express, or NestJS featuring request validation, rate limiting, caching layers, and comprehensive OpenAPI or GraphQL schema documentation. We've built API platforms serving 10M+ requests per day for marketplace startups in Berlin, healthtech companies in Boston, and B2B SaaS providers across the Netherlands.
Real-Time Communication Systems
WebSocket servers with Socket.IO or ws for live chat, notifications, and multiplayer experiences. Pub/sub architectures with Redis for horizontal scaling across multiple Node.js instances. Delivered real-time features for collaboration tools in Stockholm, trading platforms in London, and social apps with users across the US and EU.
Microservice Architectures
Event-driven microservices communicating via message brokers — RabbitMQ, Kafka, or SQS. Each service independently deployable with its own database, health checks, and circuit breakers. Built microservice ecosystems for insurance platforms in Munich, logistics companies in Rotterdam, and payment processors in New York.
Serverless & Edge Functions
AWS Lambda, Vercel Functions, or Cloudflare Workers for compute that scales to zero and responds in milliseconds. Image processing, webhook handlers, scheduled tasks, and API gateways — all without server management. Deployed serverless backends for media companies in Paris, startups in Austin, and enterprise clients requiring EU-region execution.
Background Job Processing
BullMQ and Redis-powered job queues for email delivery, PDF generation, data synchronization, and long-running computations. Priority queues, retry strategies, dead letter handling, and admin dashboards for monitoring. Built processing systems handling 1M+ daily jobs for e-commerce platforms in Amsterdam and workflow automation tools in San Francisco.
BFF & API Gateway Layers
Backend-for-Frontend services that aggregate multiple downstream APIs into optimized payloads for web and mobile clients. Authentication middleware, response caching, and request coalescing reduce latency and simplify frontend data fetching. Implemented for multi-platform products in Copenhagen, Hamburg, and across the US market.
Expertise
How we work with Node.js.
Event Loop & Async Patterns
We write non-blocking code that maximizes the event loop — proper async/await usage, stream processing for large payloads, and worker threads for CPU-intensive tasks. No thread pool starvation, no unhandled promise rejections, and no memory leaks from unclosed handles. Performance profiled with clinic.js and 0x.
NestJS & Modular Architecture
Enterprise-grade applications with NestJS using dependency injection, decorators, and modular boundaries. Guards for authorization, interceptors for logging and caching, pipes for validation — clean separation of concerns that scales from a single module to hundreds. We follow DDD patterns when domain complexity warrants it.
Database Integration & ORMs
Prisma, Drizzle, or TypeORM with connection pooling, migrations, and query optimization. We design database access layers with repository patterns, transaction management, and read replica routing. EU-deployed databases get the same performance tuning with data residency compliance built into the connection layer.
Authentication & Security
JWT and session-based auth with Passport.js or custom middleware. OAuth 2.0 / OIDC integration with providers like Auth0, Clerk, or Keycloak. Rate limiting, CORS policies, helmet headers, input sanitization, and CSRF protection. Security audits with npm audit and Snyk integrated into every CI pipeline.
Containerization & Deployment
Multi-stage Docker builds with Alpine base images for minimal attack surface and fast pulls. Health check endpoints, graceful shutdown handling, and 12-factor app configuration. Deployed on AWS ECS, Google Cloud Run, or Kubernetes with auto-scaling, rolling updates, and EU-region options for GDPR data residency.
Why us
Why TBI for Node.js.
Onboarded in Days, Not Weeks
Our Node.js engineers have shipped backends across Express, Fastify, NestJS, and serverless runtimes. They understand your framework's conventions, middleware patterns, and deployment model before writing their first line of code. Typical time to first merged PR: 2–3 days.
AI-Augmented Development
AI tools excel at Node.js boilerplate — route handlers, middleware chains, validation schemas, and test scaffolds. Our engineers use Cursor and Copilot to generate these patterns, then focus their expertise on architecture decisions, performance tuning, and edge-case handling that AI can't reason about.
US & EU Timezone Overlap
From IST (UTC+5:30), we maintain 4–6 hours of CET overlap and 3–4 hours with US Eastern. Backend incidents get immediate attention during shared hours. Deployment coordination, architecture discussions, and code reviews happen synchronously — not buried in async comment threads.
GDPR-Compliant by Default
Node.js backends handling EU data follow GDPR from the first commit. Middleware for consent verification, encrypted PII storage, audit logging for data access, and EU-region deployment. We sign DPAs and implement data retention endpoints — right-to-deletion is an API route, not a manual database operation.

FAQ
Common questions.
What does it cost to hire a dedicated Node.js developer offshore?
Dedicated Node.js engineers start at $5,000/month for full-time roles. Senior backend engineers with microservices, real-time, or NestJS expertise range from $6,000–$9,000/month. Compare that to US-based Node.js developers at $150,000–$200,000/year or EU-based engineers at €85,000–€125,000/year. Our pricing covers full team integration — Slack, GitHub, daily standups, sprint participation — with the flexibility to scale month-to-month.
How quickly can a Node.js developer start shipping on our project?
2–3 days from kickoff to first merged code. We pre-match engineers to your Node.js stack — runtime version, framework, ORM, message broker, deployment target — so they arrive ready to contribute. They study your API contracts, coding standards, and architecture docs before onboarding day. No hand-holding period.
How do your Node.js developers handle high-concurrency workloads?
We design for the event loop: non-blocking I/O by default, worker threads for CPU-heavy tasks like PDF rendering or image processing, and clustering for multi-core utilization. For horizontal scaling, we use stateless service design with Redis for shared state and session storage. Load testing with k6 or Artillery validates throughput targets before production deployment.
How do you ensure GDPR compliance in Node.js backends?
Middleware enforces consent checks on data processing routes. PII is encrypted at the field level with envelope encryption. Audit logs track every data access event. Right-to-deletion and data-export endpoints are built as standard API routes. Infrastructure deploys to EU regions (AWS eu-central-1, eu-west-1). DPAs are signed before any EU data handling begins.
What timezone overlap do your Node.js engineers provide?
Our engineers work from IST (UTC+5:30), overlapping 4–6 hours with CET and 3–4 hours with US Eastern. Backend services need real-time collaboration for incident response and deployment coordination — our overlap ensures we're available for critical windows. We adjust schedules for sprint events, production releases, and on-call rotations as needed.
