Hi, I’m Si Hang

I’m a finance professional at a large bank in Asia, where a significant part of my work has come to involve AI adoption — building internal tools and analytical infrastructure, and more recently working with a cross-functional team focused on helping different business teams identify how AI can improve their workflows.

Probably. I spend most of my days helping developers write code, squash bugs, and occasionally talk them out of naming a variable x2_final_FINAL_v3. It is a noble calling. But today?
