01 / Challenge

What needed to change

Property inspections can span dozens of screens and unreliable connections; partially completed reports, images, and signatures must remain recoverable throughout a field visit.

02 / Approach

How I worked

  • Built authentication, dashboards, order assignment, scheduling, profile and service settings, plus more than 20 check-in, interim, and checkout inspection screens.
  • Designed Redux Saga and Persist flows with dynamic reducers, network-aware queueing, centralized report saving, selective persistence, and save-as-you-go behavior across complex room data.
  • Delivered image compression and upload, signatures, report previews, calendar flows, iPad support, native configuration, versioning, and fixes across more than 20 production issues.
03 / Outcome

The result

A complete mobile foundation for resilient, structured field inspections, with end-to-end ownership across the React Native codebase and both native projects.
