NestJS development services — enterprise structure, solo delivery
APIs, microservices, worker pipelines. Built by someone who shipped NestJS at $1B+ unicorn scale. Fixed monthly price.
Who this is for
Funded startup whose backend needs enterprise-grade structure without hiring a 6-person team.
The pain today
- Express is too loose; auth, modules, queues, and docs are inconsistent.
- Handling microservice boundaries consistently is a full-time problem.
- Hiring a 6-person backend team to ship what one senior can deliver is overkill.
- Your NestJS codebase has four ways of doing every common pattern.
The outcome you get
- A senior NestJS engineer on monthly subscription.
- A NestJS codebase with one pattern for each common problem.
- Queues, workers, and microservice transport decided and documented.
- OpenAPI docs generated and kept in sync automatically.
What gets built
NestJS engagements cover: REST or GraphQL APIs, microservices (TCP, Redis, Kafka, NATS), worker pipelines (BullMQ, SQS, Kafka consumers), authentication and authorization (Passport, JWT, session, OAuth, custom guards), data layer (Prisma for Postgres, Mongoose for Mongo), OpenAPI documentation kept in sync, testing (Jest unit plus Supertest integration plus end-to-end), observability (structured logging, OpenTelemetry, Sentry), and deploy (Docker plus AWS or Vercel or Fly.io depending on fit).
Proof it works in production at bolttech scale
bolttech Payment Service on NestJS plus React plus MongoDB plus Redis plus TypeScript integrated 40+ payment providers across Asia and Europe. Shipped at 99.9% uptime, 15+ new international markets, zero post-launch critical bugs. That is a NestJS service under real load, with money on the line, across multiple microservice boundaries. The patterns used there are the patterns I bring to new NestJS builds — provider adapters, idempotency keys, structured event logs, async webhook handlers. It is proven at unicorn scale.
Timeline and delivery cadence
$3,499 per month flat. 2 to 4 day delivery cycles. Daily async updates via Linear or Jira. Weekly 30-minute call. Typical timelines: REST API with auth plus one business domain in 3 to 5 weeks. Mid-size NestJS backend with queues plus 5 domains plus frontend integration in 8 to 12 weeks. Microservices extraction (one service out of the monolith) in 4 to 8 weeks. 14-day money-back. Cancel anytime after.
When NestJS is the right call
Pick NestJS when: the team values structure and dependency injection over maximum flexibility, the domain is complex enough to justify the module discipline (fintech, B2B SaaS, multi-tenant), you want OpenAPI docs for free, or you are planning microservices eventually. Pick raw Express or Fastify when: you are shipping a 6-endpoint service and the NestJS overhead is not worth it.

Frequently asked questions
The questions prospects ask before they book.
- Can you migrate from Express to NestJS?
- Yes. Incremental migration by keeping Express as the host and mounting NestJS routes one domain at a time. Typical migration 6 to 12 weeks depending on endpoint count.
- Do you handle GraphQL?
- Yes. Code-first with the NestJS GraphQL module, schema-first when the team prefers. Apollo Federation when services need to compose.
- Testing strategy?
- Jest for unit tests on services and utilities. Supertest for HTTP integration tests against NestJS modules. Playwright for end-to-end if there is a frontend. Critical-path coverage, not vanity 100%.
- OpenAPI docs?
- Yes. The @nestjs/swagger module generates OpenAPI from decorators. The docs live at /api and update every deploy.
- Do you deploy to AWS or Vercel?
- Both. AWS ECS or Fargate with Pulumi is the default for heavier workloads (bolttech was AWS). Vercel for lighter NestJS services with Next.js frontends. Fly.io for startups that want simpler ops.
