I’m a front-end developer and former New Yorker currently living in beautiful Boulder, Colorado. I currently build websites and apps for some of the biggest names on the internet with 10up. Want more info? Get in touch!

Building Things

code, words, music

I’m a Lead Front End Engineer at 10up specializing in front-end technologies, including JavaScript, React/React Native, HTML/CSS, WordPress, and mobile application development. Prior to 10up, I worked for seven years as a front-end developer and editorial production manager at The New Yorker, where I was part of the team that rebuilt newyorker.com in WordPress.

When I’m not writing code, I like to spend my time exploring the outdoors, playing and writing music, or getting lost in a good book, movie, or video game.
