Healthcare Systems Engineer

Operational healthcare systems, built from inside the workflow.

I spent years on hospital and rehab floors before I wrote the software for them.

Systems second.' and a clinical-needs-to-better-outcomes flow, a hand typing on the trackpad, and a notebook sketch of the operational flow next to a 'Built with: Python, FastAPI, PostgreSQL, Redis, React' note.

Featured work

Four systems where the hard part was in the data layer: tenant isolation, encrypted-but-searchable identity, an append-only ledger, and retrieval that knows when to refuse.

Multi-Tenant Clinical Equipment Tracking

Running across 4 Vancouver Coastal Health sites, tracking 800+ wheelchairs and clinical assets through an 11-state lifecycle the database enforces directly — so a transition that skips a step, or a role that is not permitted to make it, simply cannot be written.

  • Live across 4 Vancouver Coastal Health sites, tracking 800+ assets
  • An 11-state request lifecycle whose transitions are gated by role in the database
  • Postgres row-level security isolating every tenant, enforced below the API
  • QR scanning driving intake, assignment, and return from the floor

HEALTHCARE / REGULATED DATA

MEPP 2.0 — Equipment Provisioning

PrototypeCase Study

Provisioning system-of-record where vendors structurally cannot receive patient identity. Encrypted PHI stays searchable through a keyed blind index, and row-level security is forced at the database role.

PrototypeAI-AssistedCase Study

Retrieval-grounded clinical answers with page-level citations — and a refusal path engineered so the model says what it is missing instead of improvising from memory.

Let's build the next healthcare system.

I'm running a multi-site hospital equipment-tracking and analytics system in production, and I'm open to healthcare data, analytics, AI, and application engineering roles — remote, hybrid, or on-site. The best way in is a short conversation.
