Node.js and Express Backend Development
Fast, dependable Node.js APIs and services built to scale with your product.
Overview
Node.js is the right tool for most modern web backends: fast iteration, a huge ecosystem, and the same language across the stack. I design and ship Node services that survive real production traffic — typed, tested, observable, and easy for the next engineer to understand.
I build production Node.js backends — REST and GraphQL APIs, real-time services, integration layers, and background workers — with TypeScript, Express or Fastify, and clean operational tooling.
Key features
What is included.
REST and GraphQL APIs
Versioned endpoints, validated input, typed responses, and OpenAPI documentation generated from code.
Database design
PostgreSQL or MongoDB schemas, migrations, query tuning, and ORM setup with Prisma or Drizzle.
Third-party integrations
Webhooks, OAuth flows, payment processors, mail providers, and SaaS APIs wired in cleanly.
Authentication and access control
JWT, session-based auth, role-based access, multi-tenant isolation, and security middleware.
Real-time and background work
WebSockets, server-sent events, BullMQ job queues, and scheduled tasks that do not block the API.
Production observability
Structured logging, error tracking, metrics, health checks, and graceful shutdown out of the box.
Benefits
Why this matters.
- Same language, full stack
- Share types, validation, and utilities between your React front end and Node backend with zero context switching.
- Scales with your traffic
- Stateless services, horizontal scaling, and connection pooling tuned for real production load.
- Easy to hire for
- Idiomatic, well-typed Node code is approachable to most full stack engineers your team will hire next.
- Cloud-portable
- Runs on Vercel functions, Render, Railway, AWS ECS, a plain VPS, or your existing Kubernetes cluster.
Process
How the work runs.
Map the domain
Document the entities, flows, and external systems your backend will own.
Design the API
Lock the contract first — types, endpoints, errors — before writing handlers.
Implement and test
Build vertical slices with integration tests against a real database, not mocks.
Harden
Add observability, rate limits, retries, and graceful degradation for downstream failures.
Deploy and document
CI/CD, environment promotion, runbooks, and handover docs for your team.

FAQ
Frequently asked questions.
- Express, Fastify, or NestJS?
- Express for small focused services, Fastify when raw performance and built-in schema validation matter, NestJS when the team prefers an opinionated structure. I default to Fastify for new APIs.
- Can you integrate with my existing Python or .NET services?
- Yes. Node services can sit alongside Python, .NET, Go, or Java backends via REST, gRPC, or message queues. I have shipped polyglot architectures and can advise on boundaries.
- How do you handle background jobs?
- BullMQ on Redis for most workloads, or native cloud schedulers (AWS EventBridge, Vercel Cron) for simpler periodic tasks. Both come with retry, backoff, and dead-letter handling.
- Do you write tests?
- Yes — integration tests against a real Postgres instance, unit tests for pure logic, and contract tests for external APIs. Coverage targets are agreed up front.
