Hire Mobile Engineers
Field apps that work without signal.
A field app is judged in a basement, a warehouse or a site office with one bar of signal. If the app assumes connectivity, the person stops using it and goes back to photographing things on their personal phone and sending them by message — which is exactly the problem it was bought to solve.
So offline is treated as a contract, not a feature: writes queue locally, sync is idempotent, conflicts resolve to a defined rule rather than last-writer-wins, and the queue survives a force-quit.
React Native Developers
Mobile engineers who ship apps that keep working in warehouses, on shop floors and in vans with no signal.
Flutter Developers
Flutter engineers who get one codebase across both platforms without it feeling native to neither.
iOS Developers
iOS engineers who build native apps that meet Apple's review bar and keep meeting it after each release.
Android Developers
Android engineers who handle the device fragmentation that comes with any real field deployment.
PWA Developers
Engineers who use progressive web apps where they genuinely beat shipping a native binary.
What to look for when hiring
Ask what happens when the same queued action is retried twice. If the answer does not involve idempotency, the app will eventually double-count something.
