Matthew Duff Learning, writing, and building in the open

About Me

Currently

Matthew Duff

I live in Denver, CO. I am married to the imitable Kylee Duff. We have four children and two pups. I really like to 🚴‍♀️, 🏊‍♂️, and play 🏀. I love eating at great fast casual restaurants.

I stopped working for larger tech companies in order to make a few small bets. I want to build a more calm life for me and my family. I previously worked at LaunchDarkly leading the Professional Services organization. Before that I worked at GitHub as the Director of Delivery and the Director of Communities of Practice and Advanced Security in the Professional Services department. I worked at MX before that doing Implementations and such with banking customers.

My largest interests outside of work are:

  • Health and fitness: I am trying to consistently work out, do long sessions of cardio, and eat healthy foods in reasonable portions. I have varying levels of success with this.
  • Liveable cities: Primarily focused on better transportation options, removing zoning restrictions, and make more walkable/bikeable cities. Check out my Twitter account for better Littleton streets
  • Building better buildings: Check out my Youtube channel about building a Passive House

From whence you came?

I grew up in rural Poland Spring, Maine. Our family moved there from Boston, Massachusetts when I was starting kindergarten. We lived on a dead end road that we made through the woods, Duff Road. It was a small town with some great people. I am the first male in my family to finish high school and the first to graduate from a university.

Dead End

Since graduating high school I’ved lived all over the western United States. The west is home for me now.
