Frequently Asked Questions

How quickly can a Node.js developer join?

Around five to seven days from the readiness audit to a matched engineer working in your repo.

Do your engineers work in plain Node or a framework?

Both. NestJS is our default because it keeps large Node backends structured and testable, but we also work in Express and Fastify codebases as they stand.

Can they take over an existing backend?

Yes. Inheriting a live backend, mapping it, and improving it without breaking production is a common starting engagement - the paid trial usually begins exactly there.

What does it cost to hire a senior Node.js developer through LogicFlow?

One monthly rate per engineer that covers the work, our management overhead, and replacement cover - no recruiter or placement fees at any point.

What does the commercial model look like?

A simple monthly rate per engineer, no recruiter or placement fees, a two-week paid trial up front, and a 30-day exit at any time after.

What happens if the engineer is not a fit?

You exit any time on 30 days notice. If the problem is the person rather than the engagement, we replace them from our own team and run the handover ourselves so your roadmap does not stall.

Do your Node.js developers overlap with US and European hours?

Yes. You get a guaranteed overlap of at least four hours with a US working day and full overlap with UK and Western Europe, so standups, reviews, and pairing happen inside your hours.

Who owns the code and IP?

You do, from day one. Every engagement assigns all work product and IP to your company, with NDAs signed before any code access and the contract held by our US-registered entity, LogicFlow International LLC.

What does AI-augmented actually mean here?

Every engineer works with our internal AI workflow toolkit for scaffolding, tests, and review support. The engineer makes the architecture calls; the toolkit removes the slow parts.
