I am co-founder and CTO at Sparkwise, where I lead product and engineering. At Sparkwise, we help develop world-class teams and leaders through multiplayer challenges.

From 2019-2021, I served as the founding CTO at Calbright College. Calbright is a fully-online competency-based college in the California Community Colleges system designed for working adults who lack easy access to traditional forms of higher education.

Before this, I served as Chief Learning Scientist at Minerva Project. I joined Minerva as Employee #1 in 2012, and spent 7 years creating new tools to support learning and teaching, including Minerva's first Active Learning Forum, tools for formative assessment, and collaborative curriculum authoring system.

In 2010, I built Studio Sketchpad, a place for creative coders to collaboratively create interactive animations in Processing (and later P5.js.) In addition to serving as a venue for informal learning, Sketchpad has been used by 100+ universities, high schools, and coding workshops. Notably, this service has been running for 13+ years.
