Where these experts contribute

  • Products used in the field — offline, location, camera, rugged conditions.
  • Consumer apps where store ratings and release discipline matter.
  • Cross-platform builds where one codebase must serve both stores.

When to hire a mobile developer

  • Mobile is a primary product surface, not a companion.
  • You need store-release ownership and crash/performance discipline.
  • Offline use, maps, or device APIs are core to the workflow.

When another path is safer

  • A responsive web product may not need a native app at all — web development first.
  • Backend-heavy products with a thin app need back-end capacity first.
  • Separate iOS and Android specialists beat one stretched generalist at scale.

Skills and evidence to evaluate

  • Shipped applications with store-release ownership.
  • Exact feature responsibility on referenced apps.
  • Crash, performance, and battery practices in production.
  • Offline patterns: caching, queued sync, conflict resolution.
