Cross-platform apps in React Native and TypeScript — ideal when your team already lives in JavaScript, or when the app should share logic with your web product.
From the Otto case study
A good fit for
- Companies with an existing React or Node.js team
- Products that share logic or design with a web app
- Apps that benefit from over-the-air updates
Tools I use
React Native · Expo · TypeScript · Reanimated · React Query · Zustand · EAS
Expo or bare workflow
Expo for speed and over-the-air updates; bare React Native when native modules demand it.
Typed end to end
TypeScript across the app and API, so whole classes of bugs never reach users.
Shared logic with web
Reuse validation, API clients and business rules with your React or Next.js site.
Smooth animations
Reanimated and gesture-driven interactions that run at native frame rates.
Over-the-air updates
Ship fixes in minutes with EAS Update, without waiting for store review.
Store releases & CI
EAS Build, automated testing and both store listings handled.

Launch & stay
Store release, monitoring and steady improvements once real users arrive.
Yes. With the new architecture, React Native apps are fast and reliable — it powers apps at Meta, Microsoft, Shopify and Discord.
Yes. I often build the app while sharing types and API code with an in-house web team, and document everything so they can contribute.
With Expo’s EAS Update, many fixes and content changes reach users in minutes without a new store submission — within Apple’s and Google’s rules.
If you need one, yes — APIs, databases, authentication and admin tools. See backend development.
