NestJS specialist or generalist - which should you hire?
The honest answer is: it depends on the half-life of your NestJS surface area. If your roadmap leans heavily on modular rest and graphql backends with clean dependency injection and you expect to keep investing in TypeScript over the next 18-24 months, a specialist will out-deliver a generalist on day-30 throughput and incident response.
If your team is smaller than ten engineers, or NestJS is one of three or four core technologies, hire a strong generalist who has shipped NestJS in anger at least twice. The cross-stack pattern recognition will pay for itself the first time you need to integrate Node.js with another part of the system.
On Haystack we surface both - filtered by whether the candidate self-identifies as a NestJS specialist and verified against their last two roles. Expect to pay around £70k–£90k for a mid-level UK hire, scaling toward £95k–£135k for senior.
