Nearshore app development: senior web and mobile squads on US hours
Senior Latin American product squads that build and ship your web and mobile apps together, working live with your product team on US business hours.
By the Ryz Labs team · Updated October 2026
Ryz Labs does nearshore app development with senior product squads that build your web app, your iOS and Android apps and the APIs behind them as one team. Our engineers are in the top 1% of the tens of thousands we interview, are based in Latin America, and work on US business hours, so design reviews, standups and code review happen live with your product team, not overnight.
What we build
Nearshore application development works best when one squad owns a product across surfaces. These are the apps our squads build and keep shipping.
- Web and mobile versions of one product: a Next.js or React web app plus React Native, Flutter or native iOS and Android apps, sharing one API, one design system and one release plan.
- Customer portals and account apps: sign-in, profiles, billing, documents and notifications, with role-based access and audit-friendly change history.
- Internal operations apps: dashboards, back-office tools and approval workflows that replace spreadsheets, often with an offline-capable mobile companion for field staff.
- Marketplace and booking apps: search, listings, scheduling, payments through Stripe or Adyen, and messaging between two sides of a market.
- App rebuilds: moving a legacy web app or an aging native app to a modern stack, screen by screen, while the old version keeps serving users.
- Shared back ends: versioned REST or GraphQL APIs, auth, push notifications and background jobs that serve web and mobile clients without breaking older app builds.
- AI features inside the app: streaming chat, search and summarization screens built on Anthropic or OpenAI models. For larger AI systems, an AI pod team takes the lead.

Why nearshore changes how an app gets built
App work is full of small decisions: how an empty state reads, what happens when a payment fails, whether a filter belongs on mobile. On an offshore team, each question waits a day. With a nearshore squad on your hours, the designer, the product manager and the engineer settle it on a ten-minute call and the change ships that afternoon. Our nearshore vs offshore guide covers the trade-off in depth.
Mexico City and San José sit one or two hours behind New York. Bogotá and Lima match New York in winter. Buenos Aires, Montevideo and São Paulo run one or two hours ahead. Every one of those cities shares most of a US workday.
How an engagement works
- Talk. We review the product, your designs or Figma files, the current codebase if there is one, and how you release today: who approves, how often and what breaks.
- Match. We propose a squad with names and a monthly price, sized to the surfaces you need (web, iOS, Android, back end) and the design and QA work involved.
- Join. The squad works in your repos, Jira or Linear, Slack and Figma, joins your standups and sprint reviews on US hours, and adopts or sets up your CI/CD.
- Grow. Add a platform, split into two squads, or hand the app over to your in-house engineers with docs and a clean backlog.
Week 1 means local builds, CI access, accounts for App Store Connect, the Play Console and your hosting, and a walkthrough of the backlog with your product lead. Month 1 usually includes the first production web deploys and a first mobile build in TestFlight or a Play internal testing track. By month 3, the squad runs a steady cadence: web changes deploy continuously behind flags, and mobile ships on a regular release train with staged rollouts. Pace depends on scope, design readiness and your onboarding.
The stack our teams work in
| Layer | Tools we use | Notes |
|---|
| Web front end | React, Next.js, TypeScript, Angular, Vue, Tailwind CSS | Shared design tokens with mobile where it makes sense |
| Mobile | React Native (Expo), Flutter, Swift and SwiftUI, Kotlin and Jetpack Compose | Cross-platform or native, chosen per product |
| Back end and APIs | Node.js, Python, Java, Go, Postgres, Redis, REST, GraphQL | Versioned contracts that serve every client |
| Cloud and hosting | AWS, Azure, Vercel, Firebase | Your accounts, your infrastructure as code |
| CI/CD and release | GitHub Actions, fastlane, EAS Build and Update, Xcode Cloud | Preview builds for every pull request |
| Testing | Jest, Playwright, Detox, Maestro, XCTest, Espresso | End-to-end tests on the flows that make money |
| Flags and monitoring | LaunchDarkly or Unleash, Sentry, Crashlytics, Datadog | Every release watched, every risky feature behind a flag |
| Collaboration | Figma, Jira or Linear, Slack, Loom | Live during your hours, written for async handoff |
How we keep web and mobile releases in sync
The hard part of building one product across web and mobile is not writing the code. It is keeping three clients, one API and one roadmap from drifting apart. These are the failure modes a senior squad plans for.
- API changes that break old app builds. A web deploy updates every user at once. A mobile release does not. Our squads version APIs, add fields as optional, and run contract tests (OpenAPI schema checks or Pact) in CI so a back-end change cannot silently break the iOS build from two months ago.
- Features that land on web weeks before mobile. Work is planned per feature, not per platform. A feature flag keeps it dark on every surface until web and mobile are ready, then turns it on together.
- Review queues that stall the sprint. Small pull requests, preview environments for every change (Vercel previews for web, EAS Update channels or TestFlight builds for mobile), and same-day code review during your hours keep work moving.
- Release day surprises. Web ships continuously behind flags. Mobile runs a release train with a fixed cut-off, a regression pass on real devices, and App Store phased release or Play staged rollout, paused if crash-free sessions drop.
- Design drift. Shared design tokens and a component library in Storybook keep the web app and mobile apps from slowly turning into two different products.
- Knowledge stuck in one head. Architecture decisions go into short written records, and runbooks cover deploys, rollbacks and on-call, so your team can own the app later.
Test coverage sits with the squad, but for larger programs a dedicated QA engineer owns regression suites and device coverage.
Team shapes and cost
Typical Ryz cost is $7,000–$15,000 per engineer per month, mostly mid-level to senior: mid-level (comparable to Amazon L5) $7,000–$10,000, senior (comparable to Amazon L6) $10,000–$15,000, and leads $15,000+, quoted per team.
- Starter pair: 2 senior full-stack engineers who build a web app and a cross-platform mobile app on one codebase family. 2 × $10,000–$15,000 = $20,000–$30,000 per month.
- Product squad: a tech lead, 2 senior web or full-stack engineers, 2 senior mobile engineers and 1 mid-level QA engineer. 4 × $10,000–$15,000 = $40,000–$60,000, plus 1 × $7,000–$10,000, plus the lead at $15,000+, so roughly $62,000–$85,000+ per month.
- Two squads: one for web and one for mobile, each with its own lead, sharing a back-end engineer and a product designer. Priced per team once scope is clear.
Project cost is team size × duration × monthly rate. A starter pair for four months at $12,000 each is 2 × 4 × $12,000 = $96,000. You get a scoped plan, a price and the names of the people before you start.
Dedicated team or staff augmentation?
A dedicated development team fits a new app, a rebuild, or a product line you want one squad to own from design handoff to store release. Staff augmentation fits when you already have a product lead and an engineering manager and need more senior hands: full-stack developers or React Native developers who work on your team and follow your release process. If you are comparing locations first, start with hiring LatAm developers.
When Ryz isn't the right fit
If you want a quick prototype from a self-serve freelance marketplace, or a no-code app builder, those are simpler starting points. If you need engineers on European or Asian hours, or follow-the-sun coverage, a global network fits better. And if you need a branding agency to create your visual identity from scratch, start there and bring us the designs.

FAQ
What is nearshore app development?
It means your app is built by engineers in a nearby country who share most of your workday. For US companies that usually means Latin America. With Ryz, a senior squad builds your web and mobile apps on US business hours and works live with your product team.
How much does nearshore app development cost with Ryz?
Typical cost is $7,000–$15,000 per engineer per month, mostly mid-level to senior, with leads at $15,000+ quoted per team. Total cost is team size × duration × monthly rate: a 5-person squad for six months at an average of $12,000 is $360,000.
How fast can a squad start?
After the scoping call we propose a team with named engineers. Most of the timeline depends on scope, design readiness and your onboarding, including access to your repos, cloud and developer accounts.
Can one squad build both the web app and the mobile apps?
Yes, and that is usually the point. One squad that owns the API, the web app and the mobile apps keeps features, data contracts and release dates aligned across every surface.
Who owns the code and the store accounts?
You do. Code lives in your repositories, infrastructure runs in your cloud accounts, and apps publish under your Apple Developer and Google Play accounts.
