I build things and lead teams that build things. Previously led engineering for user-facing apps at Polygon, and led engineering for the Blockchain team at Shopify.

I like adventures and I like solving problems. In my 28 year career I have built many products, led software development teams and organizations, led technology at a startup with a successful exit, founded and operated a successful company for almost a decade, and helped lead and scale one of the fastest-growing large engineering organizations in the world at Shopify. I have created popular open source projects, organized conferences with hundreds of people, built a successful training program, and built trust with all whom I have worked with.

I love to talk about software engineering and building great products, the business of technology, and anything related to blockchain tech. If you're working on similar things, or have an interesting technology, process, or culture problem/opportunity send me a message and let's talk.
