About me
Technically deep, genuinely joyful.
I'm Xiaole (Charlotte) — a rising senior at Northeastern studying CS + Math. I specialize in post-training as an ML engineer, with deeper focus on reinforcement learning. Beyond ML, I'm drawn to infra, systems, and building products that feel as good as they perform.
Off-screen, you'll find me on the volleyball court, learning choreography, or somewhere on a trail.
