Hire Offshore Node.js Developers

API & microservice development

• • Build REST and GraphQL APIs in Express, NestJS, or Fastify with strict TypeScript types end-to-end
• • Split monolithic services into domain-bounded microservices communicating over gRPC or message queues
• • Document endpoints in OpenAPI so frontend and mobile teams can generate typed clients automatically

Database modeling & queries

• • Design PostgreSQL and MongoDB schemas through Prisma, TypeORM, or Mongoose with reversible migrations
• • Tune slow queries using EXPLAIN plans, composite indexes, and connection pool sizing in PgBouncer
• • Implement row-level security, soft deletes, and audit trails for compliance-sensitive tables

Async, queues & real-time work

• • Wire up background jobs in BullMQ, Agenda, or Temporal with retries, dead-letter queues, and idempotency
• • Build WebSocket and Server-Sent Events channels in Socket.IO or ws for live dashboards and chat flows
• • Handle streaming uploads, chunked responses, and backpressure on high-throughput endpoints

Testing & type safety

• • Write unit tests in Jest or Vitest with Supertest for HTTP contracts and Testcontainers for integration runs
• • Enforce type safety through shared TypeScript packages so the database, API, and client stay in sync
• • Run mutation testing with Stryker on critical business logic to catch missing assertions

Production ops & observability

• • Instrument services with OpenTelemetry, structured logs in Pino, and Datadog APM dashboards
• • Debug memory leaks and event loop stalls using clinic.js, heap snapshots, and flame graphs
• • Run on-call rotation for the services they own and write runbooks for every production incident

Do your Node.js developers write TypeScript or plain JavaScript?

TypeScript, by default. Every developer in our network ships strict TypeScript in production and has worked through at least one codebase migration from plain JS to TS. If you run a legacy Node project still on JavaScript we can match a developer who has done that exact migration before and will phase in types file by file through a tsconfig allowJs path rather than rewriting the world on day one. We only send a JS-only developer if you explicitly request it.

Can they design microservices or are they only comfortable in a monolith?

Both, and the right answer depends on your stage. For teams still in product-market fit we match developers who have kept a well-structured Node monolith alive to 200k lines before splitting. For teams running 10+ services on Kubernetes we match developers who have extracted bounded contexts, run gRPC between services, and handled distributed tracing through OpenTelemetry. In the kickoff call we ask how many services you run today and match accordingly.

How do they handle Node performance and scaling problems?

They profile before they optimize. Standard playbook is clinic.js doctor and flame to spot event loop stalls, heap snapshots through Chrome DevTools for memory leaks, APM traces in Datadog or New Relic for slow endpoints, and k6 or Artillery load tests to reproduce issues locally. For horizontal scaling they know when to reach for cluster mode, PM2, or just throwing more pods at a stateless service. They will not add Redis caching before measuring where the actual bottleneck lives.

Can they build real-time features like chat or live dashboards?

Yes. Most mid and senior Node developers in our network have shipped production WebSocket work through Socket.IO, ws, or uWebSockets.js, handled reconnection logic and room-based broadcasting, and dealt with sticky sessions behind load balancers. For higher-volume fan-out they have used Redis pub/sub, NATS, or Ably as the backbone. If you need chat, live cursor, collaborative editing, or presence indicators we match on that specific experience.

How much does an offshore Node.js developer cost, and who owns the code?

A full-time dedicated offshore Node.js developer starts at $2,800 per month with Remoteria for a mid-level engineer, rising to $5,200 for senior hires with architecture experience. US Node developers cost $120,000 to $165,000 per year fully loaded, so you typically save 60 to 70 percent. You own all code, commits, and IP from the first pull request. Standard NDAs and IP assignment agreements are signed before any repo access is granted, and every deploy happens on your infrastructure under your accounts.
