Client Voices

What companies say
about hiring from us.

"
★★★★★

The React engineer from WebSenor shipped our Next.js App Router migration in 6 weeks. Lighthouse went from 58 to 96. He's better than half my in-house frontend team.

VE
VP Engineering, Series-C fintech
"
★★★★★

We tried two freelancer marketplaces — got broken components and ghost-mode developers. WebSenor's React dev shipped a real design system in 8 weeks.

CB
CTO, B2B SaaS
"
★★★★★

Hooks, Suspense, RSC — they actually understand modern React, not just class components from 2018. Code reviews are an education.

Frequently Asked Questions

Everything you need
to know before hiring.

What does the 14-day SLA actually mean?
From the discovery call (day 1) to the React developer being onboarded and opening their first PR (day 14). Typical: shortlist by day 3-5, interviews day 6-10, MSA + repo access day 11-13, first commit by day 14.
How does the replacement guarantee work?
If a React developer isn't a fit, give us 5 business days notice. We send 2-3 replacement profiles within 48 hours. No replacement fee, no penalty. Most teams never need this — but it's there.
What's the typical engagement length?
Most React contracts are 6-18 months. Minimum 1 month. No multi-year lock-ins. 30-day notice to end or scale down. Many teams start with one dev and scale to a pod.
Can we hire the React developer permanently after some months?
Yes. After 12 months on contract, conversion fee is waived. Before 12 months, it's 25% of annual salary. Standard recruiter terms.
Do your React developers know Next.js, Remix, and React Server Components?
Yes. Around 70% of our React engineers ship Next.js in production — App Router, ISR, edge functions, RSC. We also have a smaller bench for Remix and Astro. Tell us your stack and we'll match for it.
What about IP, NDAs, and source code?
100% source code authorization is standard — you get complete ownership of clean, well-documented React code on completion. Standard MSA assigns all IP to you on day 1. NDAs signed before any shortlist.
How do you vet React developers?
5 steps: 1) Resume + portfolio screen, 2) Frontend screen with our senior React lead, 3) Live coding test (90 min) building a real React feature, 4) System-design round (60 min) covering state management and performance, 5) Culture-fit + reference checks. <4% of applicants pass.
Do you work in our timezone?
Yes, at least 4-6 hours of daily overlap. India team for EU / US East coverage. EU and LATAM teams for tighter US Pacific overlap. We staff to your hours and join your standups live.
