A friend once called me an “analytical romantic.” I live in the SF Bay Area and work in the tech industry, but I also love exploring, understanding, and sharing patterns across a wide variety of fields. This is my personal site where I share a little bit about myself and my interests or projects, whether professional or from my hobbies.
