Hey there, I'm Davis!

I'm a software engineer from the Greater Boston Area now living in New York City. It's a pleasure to meet you!

These days, I'm at Handshake, building human-in-the-loop evaluation systems for frontier AI. I design the tools that experts use to generate training signal and the real-time infrastructure that powers large-scale model alignment.

Before this, I spent five years at a startup called Jellyfish, creating tools for engineering managers and product teams to do their best work. It was there that I learned how to design and build software from the ground up; I worked with incredible engineers on some really hard problems, like forecasting software delivery timelines, increasing our product's retention through relentless experimentation, researching intuitive search interfaces, scaling from one engineering team to many, and learning how to build a culture that lasts.

When I'm not working, I'm climbing at VITAL, practicing yo-yo tricks, taking pictures, writing, or running in Central Park. I have strong opinions about coffee and matcha, rotate between indie pop and electronic playlists, and will happily talk about Mr. Robot for far too long.

I also write my thoughts down occasionally over on my blog.

Long ago (May 2022), I graduated from the University of Illinois at Urbana-Champaign with a degree in Stats & CS. While in college, I tried to leave my school better than I found it by:

• Co-founding an organization to create open-source software for students.
• Running a 501(c)(3) non-profit to support student entrepreneurs.
• Serving as the Head Course Assistant for the largest undergraduate CS course in the Midwest.
• Connecting with my professors/classmates and meeting wonderful life-long friends in the midst of a global pandemic.

I'm always looking for thoughtful challenges, coffee shop recommendations, and good people to have a conversation with. You can reach out to me at dbkeene.tsyc@gmail.com for anything. Thanks for stopping by!
