Senior product manager and hands-on builder
Product judgment. Hands-on delivery. Software that ships.
I lead product work at Treeline Interactive and build products of my own. Over six years I've delivered more than ten products across web, iOS, and Android, from the first conversation through launch and the operations that follow.

I map the workflow, the people in it, and the constraint that matters before software becomes the answer.
I cut the idea down to a focused first version and stay close enough to the build to make the hard tradeoffs.
Adoption, analytics, billing, support, and the next decision after launch are part of the job.
I'm a senior product manager at Treeline Interactive, and I build software of my own under Endpaper Labs.
Leading client work keeps my own projects honest about scope. Building my own apps end to end keeps my product calls grounded in what it really takes to ship and support software.
Before Treeline I ran B2B commerce implementations at WebJaguar, which QAD acquired: more than fifty client launches, including integrations with SAP, Oracle, and NetSuite. I studied history and literature at UC Santa Cruz, which is where I learned to check sources and write plainly.
I live in Orange County, California. Outside work I photograph landscapes, play chess (1800+ on lichess), and serve as president of my HOA board.
Education: BA, US History and Modern Literature (double major), UC Santa Cruz, 2018.
