Career

Build and lead a team of five modelers. Own churn, pricing, and allocation models for logistics clients; the churn suite is projected to protect ~$4M ARR this year.
2018 – 2020
Open-Data Analyst

Built the 311-response dashboards used by three aldermanic offices. Learned that a chart nobody screenshots is a chart that failed.
