FAQ

What is the real cost to hire Koa.js developers through smartbrain.io compared to in-house recruitment?

When you hire Koa.js developer talent in-house, expenses expand far beyond the salary line. Internal recruitment fees, LinkedIn ads, interview time, onboarding delays, benefits, PTO, hardware, and office overhead typically add 25-40 % to total cost of employment. smartbrain.io’s outstaffing model bundles sourcing, multi-stage technical vetting, payroll, and local compliance into a single transparent hourly rate. There are no placement fees or equity grants, and you can pause or replace resources with 10-day notice. Most clients report 30–50 % savings over an 18-month horizon while retaining full team control.

How does smartbrain.io protect my IP when I hire Koa.js developer contractors?

Intellectual-property security is baked into the process. Every outstaffed Koa.js engineer signs a strict NDA plus an invention-assignment agreement that transfers all code rights to your company. Contracts are executed under US law, and we run background checks on each specialist. Access is provisioned via your VPN and repositories, so credentials remain under your domain. We also support on-premises VDI solutions and audit-grade logging on request, giving CTOs peace of mind that trade secrets stay locked down.

Will time-zone differences slow collaboration with remote Koa.js teams?

Not at all. We curate a bench across North, Central, and South America as well as Europe and India, allowing you to choose overlap windows that fit your stand-ups. Our service-level agreement guarantees a minimum 4-hour real-time crossover with your core office, ensuring pair-programming, code reviews, and demos happen without midnight calls.

What contract terms are available if I need to scale headcount fast?

smartbrain.io offers month-to-month, quarterly, or annual agreements. You can add or release Koa.js developers with as little as 10 business days’ notice. Volume discounts kick in after the third engineer, and our bench depth means we can double your team size inside a sprint—ideal for product launches or funding milestones.

How are candidates vetted before I see them?

Each Hire Koa.js developer candidate passes a five-step funnel: CV screening, English interview, 90-minute live coding on Koa.js middleware patterns, architecture interview with a staff principal, and final culture fit check. Only the top 2 % reach client review. You receive profiles complete with code samples and recorded sessions, so you can make swift, data-backed decisions.

What happens if a developer underperforms?

Our replacement guarantee covers you. If productivity or communication fail to meet mutually agreed KPIs within the first 30 days, we will replace the engineer free of charge within 5 business days. In critical cases, we can deploy an interim resource immediately to keep sprint velocity intact.

How soon can a Koa.js specialist start on my project?

Because we maintain an always-ready talent cloud, typical kickoff is 24–72 hours after you sign the MSA and confirm scope. Our onboarding team aligns on tool access, sprint rituals, and communication channels so the developer commits code on day one, not week three.
