Hire a senior Node.js developer who owns the backend end to end
TypeScript-first Node. NestJS, Express, Fastify. 16 years. Built at $1B+ unicorn scale. Fixed monthly price.
Who this is for
Startup running a Node.js and TypeScript backend that needs senior help beyond CRUD.
The pain today
- Event-loop blockers you cannot find.
- No queue strategy — jobs run synchronously inside the request.
- No observability — structured logging, metrics, tracing all absent.
- Deploy is 'SSH and pray' — no pipeline, no rollback.
The outcome you get
- A senior Node.js engineer with 16 years of production experience.
- TypeScript strict mode applied consistently.
- A queue strategy (BullMQ, SQS, Kafka) chosen and deployed.
- Observability baseline (logs plus metrics plus traces) shipped.
Node.js across fintech and AI tooling
Node.js is in my core stack and runs across the production work: bolttech payment orchestration on NestJS plus Node.js (40+ providers, 99.9% uptime), Instill on Next.js plus Node-backed route handlers and server actions, and Cuez with Laravel plus TypeScript plus Vue where the auxiliary jobs ran on Node workers. TypeScript strict mode is the baseline. Fastify or NestJS or raw Express get picked based on the structure the domain needs — not based on what is trendy this quarter. Every service ships with structured logging plus Sentry plus basic Prometheus metrics.
Event-loop, memory, queues — where Node teams break
Three categories cover roughly 80% of the Node.js issues I find in audits. Event-loop blockers: crypto operations, synchronous JSON.parse of large payloads, synchronous file I/O inside request handlers — move to worker_threads or async equivalents. Memory leaks: closures holding references, event listeners never removed, global caches with no eviction. Queue problems: retries that explode without dead-letter queues, jobs that fail silently, queue backpressure blowing past Redis memory. Fixing these is the difference between a Node app that survives growth and one that keeps the team on-call every weekend.
What the engagement includes
Applications subscription at $3,499 per month flat covers: API design (REST, GraphQL, tRPC), framework work (NestJS, Express, Fastify), queues (BullMQ, SQS, Kafka), database layer (Prisma, Drizzle, Mongoose), authentication (Passport, custom JWT, Clerk, Auth0), testing (Vitest or Jest plus Supertest plus Playwright), observability (structured logs plus Sentry plus metrics), CI/CD (GitHub Actions plus Docker plus Pulumi for AWS), and deploy (AWS ECS, Vercel, Fly.io). I work inside an existing team or solo on a greenfield service.
Pricing and guarantees
$3,499 per month flat. 2 to 4 day delivery cycles. Daily async updates. Weekly 30-minute call. 14-day money-back inside the first two weeks — full refund, no questions. Cancel anytime after, month to month. Work Made for Hire — every commit is yours from day one. 2 to 3 clients at a time means your work is actually on my calendar — not a rounding error.

Frequently asked questions
The questions prospects ask before they book.
- Which Node versions do you target?
- Node 20 LTS by default. Node 22 on greenfield projects where the host supports it. I upgrade legacy apps from Node 16 or 18 as part of the monthly work.
- NestJS, Express, or Fastify?
- NestJS when the domain is complex enough to justify the structure. Fastify for lean services. Express only when maintaining an existing Express codebase — I do not introduce Express to greenfield work in 2026.
- ORM — Prisma, Drizzle, or raw SQL?
- Prisma for most Postgres and MySQL projects. Drizzle when the team wants closer-to-SQL control. Mongoose on Mongo. Raw SQL inside Prisma's $queryRaw when the query is the performance-critical path.
- Do you handle monorepos?
- Yes. Turborepo or Nx for Node plus Next.js monorepos. Shared types between frontend and backend via a @repo/shared package. CI caching to keep build times reasonable.
- Can you fit inside my existing Node team?
- Yes. I have joined teams at bolttech and inside startups — I follow existing conventions and ship PRs on the same process everyone else does.
