01 / MORNING
Hey, I’m Luis.
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 PRODUCT TECHNOLOGY LIFE
02 / WORK
Building
with teams.
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.

Software Engineering • Web Monitoring & Performance

03 / APPROACH
How I work.
A few things I keep coming back to.
Choose the problem.
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.
Make the tradeoff clear.
There’s usually more than one reasonable path. Make the choices and their costs visible so the team can decide with the same information.
Learn with the team.
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
Good things,
shared.
Cooking, coffee, and loved ones.
Good company, fresh ingredients, and a bit of a cooking experiment marks a pretty good evening for me.
Something good on the table.
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.
Coffee, coffee, and friends.
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.
Gin, one bottle at a time.
I love trying and collecting new gins. Gunpowder, Monkey 47, and Roku are my favorites so far.
05 / WINDING DOWN
A little time
to unwind.
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
Still curious.
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.
