Salesforce-Based AMS

An agency management system built on Salesforce for insurance sales. I owned the roadmap, specs, and discovery for a team of Salesforce Architects, and designed the integration architecture connecting it to the industry's central policy-writing system. Two sales teams and a partnerships team sold and wrote policies on it.

About

The through-line

I run go-to-market systems for a living: the attribution pipelines, lead routing, and automation that revenue teams depend on. Seven-plus years across FinTech, eCommerce, PropTech, and InsureTech, certified in Salesforce, Marketo, and HubSpot.

The projects here started as gaps in the stack: tools I needed that didn't exist. That's where the MCP operators for HubSpot, Salesforce, and Outreach came from, and the iOS app now in App Store review.

I'm completing an MBA at UCLA Anderson while running GTM at Wistia.
