About 💁

Hello! I'm Joseph R. Lewis, and I've used the "sanbeiji" handle on the Internet since at least 2001. Most of my friends call me "Joe". Since 2014, I've been working at Google as a technical writer, where I lead Andorid's privacy, security, and authentication developer documentation. I've worked in many domains as a software developer, architect, manager, writer, and researcher in the energy, security, authentication, privacy, and defense domains. I wrote a few books! I often tinker around on GitHub.

I am also a classical double bassist. I actively this instrument on weekends and perform with orchestras and chamber ensembles whenever time permits. I love to travel, hit the gym, and push my limits on my mountain bike.
