Summary
I work at the intersection of technology and business - helping organizations make better decisions about what to build, how to build it, and how to lead the teams doing the work. With 15+ years of engineering leadership and a hands-on development background, I understand both sides of the table. My approach to AI is practical and business-first: I focus on where intelligent tools actually reduce friction, speed up delivery, and create real competitive advantage.
