HI, IT’S
LUCAS YOO.
I build AI systems that do real work: agents, voice AI, and data tools people actually use. This is a living log of what I’m building and shipping.
About Me
Hey, I’m Lucas. I studied economics at USC, but I think in products. I start with the person who has the problem, design the system, then build and iterate fast.
I did product work at MindTickle and Course Hero. Since then I’ve been shipping with AI: a multi-agent pipeline that audits online stores, a voice agent that made the finals at Dream AI Hackathon, a data platform a VC investor queries in plain English, and tools for paying clients. I build with Claude Code, and I care most about the unglamorous parts: evals, approval gates, and making sure the numbers are right.
I also make content. My TikTok has reached 40M+ views.
Check out the Build Log for what I’m working on right now.
