At Scale

Why you should use React Native to build your application?

React Native enables you to build native apps for multiple platforms using JavaScript and React. It integrates tightly with native code, supports platform-specific components, and scales from MVPs to production-grade apps.

Faster time to market

Deliver features to iOS and Android at once by sharing most of your code, reducing coordination overhead and accelerating your release cycles.

Lower total cost

Reuse infrastructure, business logic, and tooling across platforms, cutting down on duplicate work and minimizing long-term maintenance effort.

COMMON CHALLENGES

What to watch out for when growing a React Native codebase?

React Native helps teams move fast—but scaling a codebase across platforms introduces tradeoffs. From upgrade hurdles to uneven platform polish, these are common challenges we help teams solve.

Stuck on old version

React Native enables shared logic, but without care teams either underuse it or overshare and compromise platform-specific UX.

Not shipping fast enough

React Native enables shared logic, but without care teams either underuse it or overshare and compromise platform-specific UX.

Could share more code

React Native enables shared logic, but without care teams either underuse it or overshare and compromise platform-specific UX.

Android support

React Native enables shared logic, but without care teams either underuse it or overshare and compromise platform-specific UX.

Getting last 10% polished

React Native enables shared logic, but without care teams either underuse it or overshare and compromise platform-specific UX.

Regressions

With shared UI and business logic, regressions in one platform can affect others, unless caught early with proper testing or CI.

FAQs

Teams building with React Native often face tough questions—about code sharing, scaling, platform-specific behavior, or getting unstuck mid-project. Here’s how we typically support teams in the thick of delivery.

Can you join our team mid-project?

Yes. With full support for Windows and macOS, React Native can deliver desktop apps that feel native, because they are.

How do you typically work with in-house developers?

We tailor the content to your team’s level, ranging from fundamentals for new joiners to deep dives into performance, architecture, and custom native integrations.

Can you help stabilize a team that’s moving too slowly?

Yes. With full support for Windows and macOS, React Native can deliver desktop apps that feel native, because they are.

What if our team isn’t sharing enough code across platforms?

We tailor the content to your team’s level, ranging from fundamentals for new joiners to deep dives into performance, architecture, and custom native integrations.

How fast can you get started?

We’re used to joining active codebases quickly and productively, most teams see impact within the first week.

Can you help us polish the last 10% of the app before release?

Definitely. We focus on the overlooked details, such as layout bugs, accessibility gaps, inconsistent animations, and device-specific issues that delay launches.
