CareLink Hybrid

2024

Offline-first mobile healthcare platform for community health workers in rural Zimbabwe with AI diagnostic assist and end-to-end encryption.

Highlights

  • SQLCipher encrypted local DB
  • Delta-sync conflict resolution
  • Gemini AI diagnostic assist with PII stripping
  • Biometric device lock

Methodology

Field research drove the offline-first data model: SQLCipher at rest, delta-sync with conflict rules, and strict PII boundaries before any cloud round-trip.

We validated with CHW pilot cohorts, then hardened biometric lock, sync telemetry, and Gemini-assisted reporting with automatic redaction. Rollout was phased by district with MoHCC-aligned checklists.
