Which React versions do your developers work with?

Every developer in our network is current on React 18 and has shipped hooks-based code in production. Most have already migrated a legacy class-component codebase to functional components and hooks, so if you are sitting on a React 16 or 17 app that needs upgrading we can match a developer who has done that migration before. We also have developers who have worked through React 19 release candidates and the server components model for clients running bleeding-edge Next.js.

Do your developers know Next.js App Router or only Pages Router?

Both. When you kick off we ask which router your project is on and only shortlist developers whose recent production work matches. For clients mid-migration from Pages to App Router we match developers who have completed that specific migration before, because the learning curve on server components, streaming, and nested layouts is not something you want to pay for while they read the docs. Tell us in the kickoff call which side of the migration you are on.

Can the developer match our state management library?

Yes. State management is one of the screening questions on the take-home. We will not send you a Redux developer if your codebase runs on Zustand or Jotai, and we will not send you a Zustand developer for an XState-heavy app. Most senior React developers have worked in 2–3 state libraries and can move between them, but we still match on recent production experience so the first PR looks like it belongs in your codebase.

How much does an offshore React developer cost, and how fast can they start?

A full-time dedicated offshore React developer starts at $2,800 per month with Remoteria for a mid-level frontend engineer, rising to $5,000 for senior hires who can own performance work and design system governance. US React developers cost $115,000–$160,000 per year fully loaded, so you typically save 60–70%. Onboarding runs 10–14 business days: we shortlist 3 vetted candidates within a week, you run the final interview, and your developer is pushing their first component PR by day 10 of kickoff.

What testing coverage do you expect or deliver?

We match your codebase standard rather than imposing a number. On greenfield work we default to meaningful React Testing Library coverage of critical user flows plus Playwright smoke tests for checkout, auth, and any money-touching paths — not arbitrary line coverage targets that reward testing implementation details. On legacy projects we ask for your current coverage bar in the kickoff call and ensure every PR meets or beats it. We will never merge a React component without at least one behavioral test if your team requires it.

How does timezone work between Boston and an offshore virtual assistant?

Your offshore hire overlaps your Boston workday from about 9am to 3pm ET, covering morning lab meetings, grant prep, and client calls. Data entry, CRM cleanup, and document prep run async overnight and are waiting when you walk into the office.

Do you work with Boston biotech, SaaS, and edtech companies?

Yes. Most Boston clients are biotech and pharma teams in Kendall Square and Cambridge, SaaS and edtech startups in the Seaport and Fort Point, and hospital research groups in Longwood. We staff grant admin, lab ops support, CRM management, and customer success roles tuned to those workflows.

How fast can a Boston business start offshore hiring?

Boston teams move on grant cycles, funding tranches, and product milestones. Book a 15-minute intro, tell us the role, and we shortlist 3 vetted candidates within 5 business days. Most Boston clients interview on day 6 and onboard by day 10, often in time for the next milestone review.

How does offshore hiring compare to Boston's local talent market?

Boston talent is among the most expensive in the country, especially in biotech and SaaS. A clinical research coordinator near Kendall closes at $78,000–$95,000 base, a SaaS customer success lead in the Seaport runs $105,000–$130,000, and lab operations coordinators at MIT-adjacent biotechs start above $80,000. Offshore hiring delivers comparable clinical coordination, grant admin, and customer success support in 5 business days at roughly 30 percent of loaded Boston cost. For clinical-stage biotechs trying to survive the post-2022 reset, that ratio is the difference between making it to the next milestone and not.

Do Boston businesses have any special requirements for offshore hires?

Offshore contractors are not US tax residents, so Boston businesses do not withhold federal or Massachusetts state income tax, do not pay MA unemployment or paid family medical leave, and do not file W-2s. The standard form is a W-8BEN collected at engagement (not a W-9, which is for US persons) governed by an independent contractor agreement. Massachusetts Independent Contractor Law (the so-called ABC test) applies to US-based workers; it does not affect offshore engagements where the worker is performing services entirely outside Massachusetts. Most Boston clients route payments through us so they never deal with international wires or DOR filings directly.
