MBA Candidate · Columbia Business School
Hi, I'm
Todd Boonyayoi.
Engineer turned product leader. 7+ years building fintech and blockchain products in Southeast Asia. Now at Columbia Business School, targeting PM and AI Product roles at product-led technology companies.
About Me
Engineer turned product leader.
After 7+ years building products in Bangkok — from software engineer at Bluebik to launching fintech features at LINE BK — I kept asking the same question: why do some products create genuine behavior change while others don't? That question led me to Columbia Business School.
I'm a computer engineer by training and a product thinker by choice, equally comfortable in a user interview and a SQL query. I'm particularly drawn to AI-native products — where the design of the intelligence layer is as important as the interface itself.
- ◆0→1 product builder: launched fraud detection eliminating $1M in losses at LINE BK
- ◆Technical depth: CS engineering background + Python, AI APIs, and full-stack experience
- ◆Cross-cultural operator: led enterprise products across fintech, blockchain, and consulting in Thailand
