Hi! I'm Dan!

I'm a Chicago-based Software Engineer. Currently working at Hashstack, a digital consultancy, and engage in backend Rails, Golang and DevOps projects.

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, hope you enjoy it.
