Lessons from building offline-first apps for government field teams

Working on international government projects changed how I think about reliability.

Assume the network is gone

Store every action locally first, then sync. The user should never wait on a spinner to save their work.

Make sync boring

Queue changes, retry with back-off, and resolve conflicts with clear, predictable rules. Boring sync is good sync.

Validate at the edge

Catch mistakes in the form, not in the database three weeks later. Required fields, formats, and sensible ranges save everyone time.

Respect the data

Government data deserves care: encrypt sensitive records on device, limit what is stored, and keep an audit trail.
