Mailchimp Audience Analytics

Small businesses open Mailchimp with one question: is my audience growing? I built the reporting that answers it, across email, SMS and WhatsApp.

About me

The best data products answer the question you were about to ask.

I came to engineering from finance and insurance, so I gravitate to products about money and metrics: reporting at Mailchimp, internal tools for 30,000 people at Nationwide, and on my own time, Meridian and Caldera. Next: a frontend role on an analytics, data or fintech team.
