About Me

Hello there, I’m Lucas, a builder working at the intersection of AI, automation, and product systems. I study economics at USC, but I think in products. I start by understanding the user, design the system, then build and iterate fast.

I’ve worked in product roles at Mindtickle and Coursera, and these days I’m building with AI. I turn LLMs into workflows, tools, and systems that actually ship, not just demos. I also create content along the way, mostly to explain what I’m building and force myself to think clearly.

I’m currently in my final semester at USC. I’m treating it less like an ending and more like a launch point.

Welcome to my site. It’s a living log of what I’m building, learning, and refining in public.
