## About

```text
At Alohaa, I architected the cloud telephony platform from scratch, from Asterisk/PJSIP call control and SIP/PSTN routing to WebRTC NAT traversal. I lead a team of six engineers building and running the platform, which handles more than 500,000 calls per day.

I built AI call analysis with the OpenAI API to generate summaries and sentiment for agent-performance dashboards, customer CRMs, and webhooks. I also developed a call-log pipeline using MongoDB change streams and RabbitMQ, with tiered storage in MongoDB and S3/Parquet.

Earlier, at Zippr, I was a core developer on the patented DDN geolocation product and built its 13-character address-code algorithm. At Accenture, I built voice and messaging flows on Twilio Flex for Philip Morris International and assisted with Salesforce integrations.
