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 San Francisco and an offshore virtual assistant?

Your offshore hire overlaps your San Francisco workday from roughly 9am to 2pm PT, which covers your daily stand-ups, customer calls on the East Coast, and morning inbox work. Everything async — CRM hygiene, research, reporting — runs overnight and is ready before your 9am Slack check.

Do you work with San Francisco SaaS startups, AI companies, and fintech teams?

Yes. A large share of San Francisco clients are venture-backed SaaS companies in SoMa, AI startups around Hayes Valley, fintech firms in the Financial District, and biotech teams in Mission Bay. We price for founder-led companies and scale with you from seed to Series C.

How fast can a San Francisco startup start offshore hiring?

SF startups run on weekly sprints and 30-day cash burn reviews. Book a 15-minute intro, tell us the role, and we shortlist 3 vetted candidates within 5 business days. Most San Francisco clients interview on day 6 and onboard by day 10, usually between board meetings.

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

SF is the most expensive software labor market in the world and the AI boom has only made it harder. A product ops hire in SoMa closes at $140,000–$170,000 base before equity, a customer success manager in the Mission runs $130,000–$165,000, and even a decent executive assistant in Hayes Valley clears $90,000. Offshore hiring delivers comparable revops, customer success, and back-office support in 5 business days at roughly 25 to 30 percent of loaded SF cost. For seed and Series A startups burning runway against ZIRP-era valuations, that ratio is the difference between making the next round and not.

Do San Francisco businesses have any special requirements for offshore hires?

Offshore contractors are not US tax residents, so SF businesses do not withhold federal or California state income tax, do not pay California SDI or unemployment, and do not file W-2s. The standard form is a W-8BEN at engagement (not a W-9) governed by an independent contractor agreement. California AB 5 worker classification rules apply only to US-based workers and do not affect offshore engagements. The San Francisco gross receipts tax applies to entities, not to international contractor payments. Most SF clients route payments through us so they never deal with international wires or California EDD filings directly.
