Overview

I've spent 12 years on data pipelines - first at Qualcomm, now at Bellmont Technologies. Brought on-call pages for data platform down from 20 a week to 3. Cut p99 latency on the data platform services from 719ms to 169ms. Before that: Intel and Bain & Company. Most at home with Python and Iceberg.
