Node.js development services — TypeScript-first, one senior
NestJS, Express, Fastify. One senior engineer covering API, queues, deploy. Fixed monthly subscription.
Who this is for
Founder who wants a TypeScript-first backend built by one senior engineer.
The pain today
- Backend-for-frontend is a full category nobody on the team owns.
- You have a React or Next.js frontend but no backend senior.
- Hiring a full backend team is overkill for current scope.
- Your last Node contractor left no tests and no docs.
The outcome you get
- A senior Node plus React engineer on monthly subscription.
- TypeScript strict mode across the whole codebase.
- Queues, auth, observability, CI/CD shipped with the backend.
- OpenAPI docs generated from the code, in sync every deploy.
What gets built
Node.js engagements cover: REST or GraphQL or tRPC APIs, NestJS or Fastify backends, microservices and worker pipelines, database layer (Prisma, Drizzle, Mongoose), authentication (Passport, custom JWT, Clerk, Auth0), testing (Vitest or Jest plus Supertest plus Playwright), observability (structured logging plus Sentry plus Prometheus basics), CI/CD (GitHub Actions plus Docker plus Pulumi), and deploy (AWS ECS, Vercel, Fly.io, Render). The default stack is Node 20 plus TypeScript strict plus NestJS or Fastify plus Prisma plus Postgres plus Redis plus Docker plus AWS — with swaps when the domain calls for them.
Two production references
bolttech runs NestJS plus Node.js at $1B+ unicorn scale across 40+ payment providers with 99.9% uptime and zero post-launch critical bugs. Instill runs Next.js 16 plus Node-backed server actions plus Postgres plus Vercel at startup scale with 30+ users, 1,000+ skills, and 45+ projects powered. Same engineer, opposite ends of the scale curve. The decisions that make sense at 10 users differ from those that make sense at 10 million — the engagement picks the right shape for your current and next-12-months traffic.
Timelines and what to expect
$3,499 per month flat. Typical timelines: REST API with auth plus one business domain in 3 to 5 weeks. Mid-size Node backend with queues plus 5 domains plus frontend integration in 8 to 12 weeks. Backend-for-frontend wired into an existing React SPA in 3 to 6 weeks. Daily async updates via Linear or Jira. Weekly 30-minute call. 14-day money-back inside the first two weeks. Cancel anytime after, month to month. Work Made for Hire — everything is yours.
When Node.js is the right call vs the alternatives
Pick Node.js when: the team is TypeScript-everywhere and you want one language across frontend and backend, the domain is I/O-bound (API orchestration, webhooks, real-time), or you want the npm ecosystem breadth. Pick Laravel when: the team is PHP-fluent and the domain is CRUD-heavy with a strong admin layer. Pick Python when the workload is ML-adjacent — but that is outside my stack. The recommendation is written during discovery and you can override.

Frequently asked questions
The questions prospects ask before they book.
- Do you cover the frontend too?
- Yes. React, Next.js, Vue on the frontend. One engineer covering both sides is the core value of the subscription model.
- tRPC or REST or GraphQL?
- tRPC for monorepo TypeScript apps with tightly coupled frontend and backend. REST for public APIs and multi-client scenarios. GraphQL for complex frontends with many clients — less common at startup scale.
- Do you handle websockets and real-time?
- Yes. Socket.IO for most cases, WS plus custom protocol for tighter control. SSE for simple server-to-client streams. Realtime pub/sub via Redis or a managed service like Ably or Pusher.
- Docker or serverless?
- Docker on AWS ECS or Fargate for most production Node services. Vercel serverless for Next.js route handlers and light APIs. Lambda only for event-driven pieces — not as the default API host.
- Cron jobs and scheduled tasks?
- BullMQ repeatable jobs when the queue is already there. AWS EventBridge or Vercel Cron for simpler schedules. Logged and monitored like any other production code.
