CareLine

A voice agent for post-discharge check-ins, with a safety layer the model can’t override.

Doctor’s log
If a voice agent skips a question, or tells a patient to dial 911 instead of Singapore’s 995, that isn’t a bug. It’s a clinical hazard.
  • The model handles the conversation; plain, testable code makes the final triage call.
  • A rule engine re-checks every triage decision. It can raise the severity, never lower it.
  • A live filter catches “911” or “999” mid-sentence and enforces Singapore’s 995.

Co-host 2.0

A live AI voice co-host that shows how an agent works while it works.

Slides don’t show how an AI agent actually behaves, so the second screen did.

Healthcare Data Journey

Hospital records and wearable data on one patient timeline.

Clinics speak HL7v2 and FHIR. Patients live in five-minute glucose readings. Care teams need both.

Neighbourhood healthy ageing model

Which neighbourhood signals actually predict healthy ageing across Singapore?

Health doesn’t start at the hospital door. It starts with shade, a clinic nearby and food within walking distance.

From a photo of a catering label to a safe lunch order.

If you have an allergy or a dietary rule, “what’s in this?” is a safety question.

Architect Copilot

An architecture assistant for healthcare and life sciences that checks its own work.

In healthcare, one wrong claim about a cloud service costs trust, so a second agent verifies it.

Pattern, not customer

No client names. No screenshots of anyone’s systems. Just the problem, the pattern and the clinical reason.
