Hi, I'm Dan.

I'm a California-based software engineer. Currently working at Apple, a tiny startup focusing on consumer hardware and services.

In my spare time I like to travel, ride motorcycles around the country, play guitar and contribute to open source projects. You can find me on GitHub, Twitter and Instagram.

This website is a personal sandbox for code and infrastructure experiments, and does not represent any of the work I do for my current employer. Hope you enjoy it.
