PRODUCT MANAGEMENT · AI · REVENUE SYSTEMS

I build intelligent systems that help revenue teams make better decisions.

I’m a Director, Product Manager at Visa, developing AI-enabled CRM products that help sellers work more efficiently and effectively. My product perspective is grounded in 15+ years building customer-journey, analytics, and growth systems at Apple, Google, and Dell.

psychology HOW I WORK 01

Start with behavior

I ask why users behave as they do before accepting a feature request or opening the dashboard. Then I use research and data to test the explanation.

query_stats HOW I WORK 02

Turn evidence into a decision

Analysis is useful only when it changes what the team builds, how it measures success, or what it chooses not to pursue.

schema HOW I WORK 03

Design the whole system

I connect data, rules, workflows, interfaces, and operating constraints so the product works beyond a single feature or launch.

groups HOW I WORK 04

Build across functions

I work across business, operations, design, data, and engineering to resolve tradeoffs and create shared ownership of the outcome.

From operating systems to building products.

I didn’t leave my previous experience behind when I moved into Product Management. I moved upstream—from operating customer and revenue systems to building the products behind them.
