Hi! My mission is to build technology that advances our civilization.

Currently, I’m a senior software engineer / tech lead at Brex, focused on card fraud. Before that, I led the development of some APIs and integrations.

You can find out more about my time at Brex on The Muse, Built In NYC, and our Careers page.

Previously, I was a backend engineer at Apple Siri Search working on TV & Flights search, and at Microsoft building cloud infrastructure & developer tools.

I love building things. My projects have received funding from Pioneer, a remote accelerator for projects and startups built by ambitious outsiders around the world.

I have a strong curiosity for the intersection of computer science and financial systems, because the creation and exchange of value is at the core of human activity. Technology has the ability (and responsibility!) to make that more efficient and accessible. I’ve enjoyed writing about these subjects for publications like Hacker Noon.

I was the first in my family to attend college. I graduated from Brown University in Computer Science & Economics, where I was also a teaching assistant, hackathon prizewinner, and founder/president of 3 student organizations.

I speak Portuguese, Mandarin, and English daily. I love to read.

Say hello at julia@juliawu.me! Thank you for stopping by.
