San Francisco · 2026
Hey! I'm Wally. I currently work at Extend as a data scientist, running pricing optimization experiments for consumer retail extended warranties. Before Extend, I was a private equity analyst covering cybersecurity and GRC at Carrick Capital.
On the side I'm building RodSmith, a knowledge-first marketplace for custom fishing rods I started in fall 2025, and also working on a smattering of small hardware projects that solve little problems I run into day to day, doorpi being the latest.
I'm passionate about fishing, and I think it won't be long until I can simply convince fish to jump into my net on command. I also bake. Bagels are the ultimate achievement for me, and I do believe I make the best bagel in San Francisco.
This site is where all these facets come together. It is not a rèsumè - rèsumès are quite boring after all. I simply hope to share a bit about myself, and if you are reading to figure out whether to email me, the short answer is yes, and the address is at the bottom!
From the gridiron to the mountains.
I've always competed in some sort of physical activity. The activity and its meaning has transformed for me over the years, but the grind remains consistent and ever valuable.
First soccer, then lacrosse, then football, and now endurance. I'm not sure why, but I think I'm addicted to the struggle.
The /sweat/ page documents the trophy days, the ones that are really memorable - this section is just the through-line.
Bagels are the trophy. Bread and pizza are practice.
Baking bread is neat because the end result is dramatically affected by so many variables. Two people could start off with the same exact ingredients and have two completely different end results come out of the oven.
Currently, bagels are the ultimate product, perhaps it's because San Francisco fails to deliver any good ones in my humble opinion. Pizza and sourdough are quite nice as well but are far more forgiving. The photos and bake notes live at /kitchen/; specifics drop in as I write them.
