About Me

Hello 👋 I'm Cat, a Computer Scientist passionate about machine learning, deep learning, and building intelligence.

Short Bio

Computer Scientist 🧑🏻‍💻 focused on machine learning, deep learning, and AI research. Passionate about reinforcement learning, mathematics, and building intelligent systems at scale.

In my free time, I love swimming, playing basketball, and exploring new places. Growing up in a coastal town, I’ve always been drawn to the sky and the ocean—and the pictures above remind me of home!
