Parts of the platform I work on at Notable Health.

My work

I work on caller verification, call routing, transfers and monitoring for the voice and conversations platform.

Working with

Python · TypeScript · Node.js · React · PostgreSQL · BigQuery · SIP · GCP · Kubernetes · Terraform

Inside the build

Connecting health systems and phone networks.

Context

Notable serves 100+ enterprise customers. Our team’s voice and conversations platform handles around 250,000 patient calls a month across EHR, FHIR, carrier and customer call-center boundaries.

How it works

I wrote the inbound SIP integration specification, covering TLS, SRTP, caller ID, DTMF and DID routing. My work also includes patient lookup, SMS verification and configurable fallback routing.

In the work

Inbound SIP currently accounts for $240k in ARR. Expansion opportunities I unlocked could take it above $1M. Caller verification is used across 5+ health systems.

Incident practice
I lead voice incident debriefs and work on recovery measures, including customer-configurable fallback routing
Flow testing
I lead AI-powered testing for the flow builder; flow success rates are above 90%
Launch impact
Multilingual conversations, configurable transfers and builder configuration cut new-customer launch time from weeks to days

Keep exploring.
