HFA — Health for All

My proudest project: a device–app ecosystem designed to help people monitor their health proactively, reduce pressure on hospitals, and improve the overall quality of healthcare services.

People actively monitor their health

Make routine measurement and tracking simple, consistent, and accessible—at home, not only at clinics.

Reduce burden on hospitals

Shift non-critical follow-ups to continuous monitoring and targeted alerts, so clinicians focus where it matters most.

Improve quality of healthcare services

Structure data, trends, and context into a clinician-friendly workflow that supports better decisions over time.

Software capabilities

From capture → structured history → reminders → collaboration

  • User & caregiver network: login, profiles, permissions, followers, follow requests.
  • Medical data management: list/detail views, graphs, CRUD, comments, diagnostic links.
  • Diagnostics: manage diagnostic entries and link them to medical data.
  • Automation: extract values from devices/prescriptions; trend analysis and alarms.
  • Integrations: HFA-careport devices (discovery/BLE data); Samsung Health linking and sync.
  • Medication workflow: prescription CRUD, reminders, push notifications, read state.
  • Assistant: chatbot via text and image with history management.
