Hire NestJS developers
Senior NestJS developers from Miyagami build structured, typed Node backends inside an opinionated framework. They're tested on module architecture, dependency injection, typed contracts and disciplined testing, first without AI tools, then with them.
01
AI writes boilerplate; engineers own the architecture
Generators and agents can scaffold a NestJS module in seconds, so engineers spend less time on boilerplate and more time on decisions. The ones who matter know when the generated structure fits the domain and when it doesn't.
02
Typed contracts matter more now
AI-generated code tends to weaken type boundaries unless the engineer holds the line, so TypeScript discipline now decides the quality of NestJS projects. Engineers who can't read and correct AI output on DTOs and interfaces ship technical debt fast.
03
Testing discipline matters more with AI
AI tools can generate tests as quickly as they generate implementation, so coverage numbers look fine while real scenarios go untested. Engineers need to judge what a test proves as well as whether it passes.
How we assess NestJS developers
Every engineer works through a fundamentals assessment with AI tools switched off and a second assessment with their own agents running. For NestJS developers, these criteria carry the most weight.
- Debugging
In a real NestJS codebase, candidates trace a broken provider graph or a misconfigured interceptor through the dependency injection system without reaching for documentation shortcuts.
- Spec-driven development
Candidates are given a typed API contract and must implement NestJS controllers, guards and DTOs that satisfy it exactly, keeping the spec as the source of truth even when other code would be easier to generate.
- AI output verification
Candidates review AI-generated NestJS code for incorrect module scoping, missing exception filters or broken pipe configurations, and explain precisely what the output got wrong before accepting or correcting it.

How to review AI-generated code
Reviewing AI-generated code changes some of what reviewers look for and keeps the rest. This entry covers both, plus the specific failure modes to check for.
What is Backend as a Service (BaaS)?
BaaS provides pre-built cloud infrastructure (databases, auth, storage, APIs) so teams ship apps without building or managing servers from scratch.
What changed about code review
AI-generated code has changed what code review looks for. This entry explains why reviews take longer and what skills reviewers now need.
Questions about hiring NestJS developers
How senior are these engineers?
The NestJS developers we put forward are senior, with 6+ years' experience on average, and they've shipped and maintained production systems in NestJS. Every one has passed both assessments, and you see both scorecards before you meet them.
How do you test NestJS specifically?
Candidates work in a real NestJS codebase across two assessments. The first covers module architecture, dependency injection, typed contracts and debugging with no AI tools. The second covers the same codebase with their own agents and tools.
How quickly can a NestJS developer start?
We aim to send you a shortlist within five working days. From shortlist to first commit is typically three weeks, covering your interview, any trial task and contract paperwork.
What does a NestJS developer cost?
You pay a fixed monthly fee of €5,600 to €8,000 per full-time engineer, with employment, payroll and compliance included and no recruitment fee. The pricing page compares it with the all-in cost of a senior local hire in your country. Engagements are full-time with a three-month minimum, and if a placement doesn't work out, we replace them at our cost.
Do they work in our tools and codebase?
Yes. They join your repositories, your communication tools and your workflows on day one. We don't embed them in a separate environment or abstract them from your team.
Get a shortlist within five working days
You share the roles and the stack in a short form or a thirty-minute call. Within five working days you get named senior engineers to review, each with both scorecards.
