Hello, I'm one of the original evangelists for Ruby on Rails and the author of The Rails Way as well as Patterns of Application Development Using AI. Over the past three decades, I’ve led teams and built products at every scale — from early-stage startups to global platforms — combining deep technical expertise with a creative, forward-looking approach to software craftsmanship.

I bring 30 years of hands-on engineering experience, including senior leadership in architecture, AI integration, and product strategy. Whether working as an individual contributor or guiding organizations through transformation, I focus on delivering clarity, velocity, and sustainable innovation. My last gig was leading AI strategy related to Developer Experience at Shopify.

Currently evaluating consulting and permanent opportunities with preference for executive leadership position at a larger company, although will consider consulting and fractional CTO type roles for startups and smaller ventures if the project and team are interesting enough.
