Field Notes

An offline-first inspection app that helps field teams record evidence and finish reports before leaving a site.

Context

Inspectors were taking photographs on site and rebuilding the report later from memory, often with weak connectivity and incomplete notes.

Contribution

I designed the mobile workflow, built the offline data layer, and worked with inspectors through three field trials.

Constraints

  • The app had to work for an entire shift without a network connection.
  • Evidence could not be lost when devices ran low on storage.

Key decisions

  • Saved each answer locally as it was entered instead of waiting for form submission.
  • Made sync state visible beside each report and attachment.

Outcomes

  • Reduced return visits caused by missing evidence.
  • Cut the median report completion time by 18 minutes.

Product engineering for operational tools and thoughtful software teams.
