I lead product org transformations—from reactive shared-service models to outcome-driven product operating models. Formally trained in Marty Cagan / SVPG principles. I'm also a voracious learner. Every project I ship teaches me something—which is exactly the point. Building things yourself is the fastest way to become a better product manager.

Active Projects

Heddlepin
Live ↗

Community exploration platform for obsessives—people who care too much about the right things and want to find their people in the real world. Pinned locations unlock full lore and community marks only when you physically show up. Built on Node.js, PostgreSQL + PostGIS, MapLibre, and Cloudflare.

What it taught me: Geographic UX is deceptively hard. The "arrive and unlock" mechanic required rethinking every assumption about how users interact with map interfaces—and forced me to feel every friction point my engineers warned me about.

Bracket Battle
Live ↗ Repo ↗

Single-elimination bracket tracker for the 2026 NCAA Men's Lacrosse tournament. 16 teams, 15 picks, one champion. Deployed as a static site—zero backend, zero dependencies, zero budget.

What it taught me: Constraints are a gift. Building with no server forced creative thinking about state, persistence, and UX that a "just add a database" approach would have skipped entirely.

Melee
In Development Repo ↗

Sports social product built around watch parties, live event energy, and the communities that form around them. Deep schema design, ontology work, and scenario modeling before a single line of product code.

What it taught me: Writing a full ontology before building anything surfaces assumptions you didn't know you were making. The design thinking docs changed the product more than any user interview did.
