I'm a Senior Engineering Manager who's spent the last decade building the teams behind the products, and the systems and culture that make shipping repeatable.

Experience

1. Since 2025

   Senior Engineering Manager · Cash App / Block

   Leading the Tax Server / Engine team. Shipped three AI product launches, transformed operational excellence (about 80% reduction in pages and tech debt), and lifted team output ~60% through team-wide adoption of AI-assisted development.

   Engineering Manager · Amazon (AWS · Freevee · Prime Video)

   Led teams of 4 to 14 across three orgs. Launched RPKI route security across all AWS routers globally, built Freevee's notification platform from zero to 5M+ customers, and delivered Prime Video with Ads in 4 months with a 14-engineer tiger team, unblocking launch to 50M+ customers.

3. 2013-2020

   Senior Manager / Principal Lead Engineer · Vistaprint

   Built the DIY website builder (Tower) from greenfield to launch with 20+ engineers, reversing a 3% signup decline into 5% growth. Formed a 30-person Design Tech org. Founded a 4-year mentorship guild that reached 100+ engineers and converted 8 ICs into managers.

Frameworks I've built

Systems and processes I invented while leading engineering teams. Some outlived me at the companies that adopted them.

• Sailboat Feedback

  An in-person session that replaces 360 surveys. 95% attendance and 10 to 20 actions per person across the teams I've run it on.

• Facets of Growth

  A peer-built career framework derived from the qualities of respected ICs. Evolved into an org-wide evaluation and coaching system at Vistaprint.

• Dependency Graphs

  Visual scoping that surfaces hidden risk before commitment. Predicted a 4-month launch estimate for Prime Video with Ads to the day.

• Swarms & Colonies

  Self-organizing team structure that turned multi-month reorgs into days. 8 to 10 rebalances in 10 months without losing people.

• TIME-entific Method

  A successor to SMART goals built for the 1:1 coaching context. Tracks habit formation and the ROI of time spent.

• Tributary

  Owner-driven status board that replaced project meetings. 20+ initiatives visible in a 30-minute weekly review.
