Product Manager • Security, Integrity & Investigations
Building tools that help teams investigate threats, report to authorities, and keep people safe.
01 / MORNING
Mostly Product.
Engineer at heart.
I work where product, engineering, and trust & safety meet. I like understanding how things work, finding the right problem, and building something useful with a team.
A lot of that curiosity carries into my free time. This is a little tour of both.
Come along for the day
02 / WORK
An engineering background.
A product perspective.
My experience spans software engineering and technical product management, with a particular interest in trust, safety, and the ways technology gets used in the real world.
Product Manager • Security, Integrity & Investigations
Building tools that help teams investigate threats, report to authorities, and keep people safe.
SWE & PM • Integrations, Trust & Safety
A move from engineering into product, focused on integrations, abuse, bots, and bad actors.
Acquired by Splunk · now part of Cisco
Software Engineering • Web Monitoring & Performance
Building software for performance monitoring and optimization, from conception through delivery.
03 / APPROACH
A few things I keep coming back to.
Before getting attached to a solution, understand who needs it and what’s actually getting in their way. A clearer problem makes the next decision easier.
There’s usually more than one reasonable path. Make the choices and their costs visible so the team can decide with the same information.
Build enough to test an idea, listen to what happens, and adjust. I like staying close to the technical details and learning alongside the people doing the work.
04 / AT HOME
Cooking, coffee, and loved ones.
Good company, fresh ingredients, and a bit of a cooking experiment marks a pretty good evening for me.
I love making my award-winning pizza, a frutti di mare pasta, a basted ribeye, or some savory panang curry, and outside of that, experimenting with ingredients in recipes where most wouldn't think of adding them.
I’m pretty crazy about coffee. I have a full espresso setup, try new beans all the time, and track their grind setting and my rating for every one of them.
About once a month, I host Big Umi Cafe: a Sunday morning coffee gathering for friends. Coffee’s on me, everyone brings pastries to share, and there’s a rotating seasonal drink. The name plays on the Japanese words for sea and wave, a nod to our dog.
I love trying and collecting new gins. Gunpowder, Monkey 47, and Roku are my favorites so far.
05 / WINDING DOWN
My favorite people. A quiet evening.
Time on the couch with my fiancée and our cavapoo. Usually something to watch, something to snack on, and a dog who’s already asleep.
One more idea
06 / AFTER HOURS
Following my curiosity. Experimenting with AI.
Some of my best learning starts with a late-night idea, my laptop, and my always-on coding Raspberry Pi. I build things to understand a technology, make a task easier, or see whether an idea works.
