I’m a software developer with over a decade of experience in both individual contributor and leadership roles, including stints in Product Management and Developer Relations. I’ve worked up and down the stack, from dynamic browser-based applications to embedded integrated circuits.

Most recently I’ve worked for Render and Heroku (Salesforce).

Although my career has been centered around software, I have a deep interest in hardware and more specifically the combination of hardware + SaaS. This interest led me to form an IoT startup in 2015. A snapshot of this work is at https://ctrl.industries.

I also love working outside. Combining technology and the outdoors is even better. Outdoor roles that I’ve previously held include ski patroller, avalanche and snow safety instructor, and bicycle mechanic.

I enjoy intellectual challenges and thrive on learning:
