I'm an engineer who loves things & exploring new ideas.

I wrote the book Machine Learning and Security by O'Reilly Media, teach at Berkeley, and co-founded a fraud data infrastructure company, Unit21. I sometimes share my ideas in AI and security through talks and workshops. I have a B.S. + M.S. from Stanford Computer Science.

I am Singaporean, but spend most of my time in the SF Bay Area now. Reach out if you want to chat -
