Hire progressive web app developers who make the web app feel installed, not just bookmarked.
Offline-first, installable web apps, service workers, caching strategy, and the performance discipline PWAs demand, by engineers who test with the network actually turned off, not just in a fast office wifi demo.
Caching strategies matched per resource type, not one blunt cache-everything rule.
Genuine offline functionality for core flows, with clear sync-on-reconnect behavior.
Web app manifest, icons, and install prompts tuned for real adoption, not ignored.
Time-to-interactive and Lighthouse PWA scores treated as launch criteria.
What strong Progressive Web App Developers know cold.

Hiring for something adjacent?
Answered before you ask.
For a lot of use cases, yes, especially when app-store distribution friction outweighs the need for deep native APIs. For anything needing heavy background processing, Bluetooth, or platform-specific hardware access, native still wins, and we'll say so.
Core flows, viewing already-loaded content, queuing an action, keep working with no connection, and sync cleanly once it's back, rather than just showing a generic offline error page.
Not quite, Android's install and push-notification support is more complete; iOS Safari has real but narrower PWA support. We scope expectations per platform honestly rather than promising full parity.
Chrome DevTools' offline mode and airplane-mode device testing, covering both the first offline visit and returning to a previously cached session, the two cases that fail in different ways.
Every way out of this hire is already written down.
Not a fit? Replace anyone in the first two weeks. No questions asked, no replacement fee. We re-match from the same vetted pool.
You pay only for engineers who actually start. Seeing candidates costs nothing.
Dedicated and managed engagements run on a monthly rolling contract. Cancel with notice.
You see the number before you commit. Nothing is added on top of it later.
Bring us the offline problem. Three matched engineers in 48 hours.
Tell us which flows need to survive a dropped connection. We'll scope the caching strategy before writing a line of service worker code.
We reply within an hour during our working day in India and the UAE.
