The problem

The health platform had to serve four groups: field health workers, hospital administrators, device managers, and insurance officers. Each group had different needs, so a weak product definition would fail in practice even if the code worked.

The challenge

Rural and semi-urban clinics were generating patient vitals on paper with no structured digital layer. The product had to account for four user groups with different priorities and levels of technical experience, then give the engineering team enough detail to build the Go API, Flutter app, three React dashboards, blockchain anchor service, and insurance portal. The audit trail also required clinical operations, legal, and engineering to agree on what counted as a tamper-proof medical event.

Problem Statement

Rural clinics generate vitals on paper - 12-24h sync delays and data loss during outages. The platform must handle concurrent writes while guaranteeing offline delivery.

Primary Users

  • Field Health Worker

    Vitals capture, offline sync, real-time alerts

  • Hospital Admin

    Real-time monitoring, report export

  • Insurance Verifier

    Eligibility checks, blockchain audit trail

  • Device Manager

    Fleet provisioning, OTA, status dashboard

Core Services

  • •Go/Gin REST API - clinical CRUD, WebSocket, auth
  • •Flutter app - offline-first sync queue
  • •Hospital dashboard - real-time vitals monitoring
  • •Insurance portal - CSV eligibility + batch jobs
  • •Blockchain anchor - Polygon Amoy audit trail

Key Acceptance Criteria

  • AC-1API uptime SLA: 99.9% measured monthly
  • AC-2p95 API latency under 150ms
  • AC-3Offline queue delivers on connectivity restore
  • AC-4Blockchain anchor fires within 30s of record
  • AC-5Insurance CSV verification under 5 min/batch
  • AC-6Hospital dashboard vitals stream under 2s end-to-end

Sprint Milestones

  • S1Go API core + PostgreSQL + auth
  • S2Flutter app + offline sync queue
  • S3Hospital dashboard + WebSocket
  • S4Blockchain anchor + Polygon deploy
  • S5Insurance portal + go-live

Results

Shipped 5 production services to a live pilot network of field health workers. API uptime SLA of 99.9% with p95 latency under 150 ms defined and met. Blockchain medical record anchoring on Polygon adopted for insurance audit trail, cutting manual cross-referencing from days to minutes. The hospital and insurance dashboards were delivered as separately deployable portals with independent auth scopes - a product decision that reduced onboarding friction for partner institutions who wanted only a subset of the platform.
