Hire React Native Developers
Mobile engineers who ship apps that keep working in warehouses, on shop floors and in vans with no signal.
React Native earns its place when the same product has to reach both platforms and stay in step with a web application built by the same team. Sazinga Field is offline-first for sales representatives who lose signal for hours, AdBoard puts operations in the hands of crews at the site, Factory runs on the shop floor and Engage delivers training on personal devices — four different reasons for the same technology choice.
When hiring, ask about offline behaviour and about the native side. What happens to a form submitted with no connection and edited again by someone else before it syncs. When did they last write Swift or Kotlin, and why. Engineers who have shipped a real fleet app talk about device fragmentation, battery and store review; engineers who have not talk about component libraries.
What these engineers do
- React Native 0.7x on the New Architecture, with Fabric and TurboModules
- Offline-first storage in WatermelonDB or SQLite with conflict-aware sync
- Native modules written in Swift and Kotlin when no library exists
- Camera, barcode scanning, geolocation and background tasks tested on real devices
- Release pipelines with EAS or Fastlane, staged rollout and over-the-air updates
Delivered AI-first
AI assistance is used for screen and navigation scaffolding, typed API clients, list and form components, and the repetitive bridging code between JavaScript and a native module. Sync logic is written by hand, because conflict resolution on an offline-first app is the part that quietly corrupts data if it is nearly right, and no test suite catches it as reliably as a careful reviewer does. Review discipline is unchanged. The measurable effect is throughput per engineer, not fewer reviews.
Built with React Native at Sazinga
These are our own production applications, not client references — which is why the engineers have operated them, not just written them.
