I've spent two decades building everything from mobile and web products to the platform architectures that power them. Somewhere along the way I became obsessed with the part of the system that never shows up in an architecture diagram: the people.
Engineering culture and DevEx dictate technical success. Today I help teams navigate the psychological shifts modern engineering demands — AI included — so they can move fast without breaking each other.
# runtime config for every team I touch psychological_safety: required trust: high velocity: high hype: null accessibility: default metrics: "the ones that matter"
-
People are the infrastructure
Culture and developer experience are load-bearing. Ignore them and the stack falls over.
-
Trust is a velocity multiplier
Psychological safety isn't soft. It's how teams ship fast and stay quick without getting dirty.
-
Measure what matters
Move past the hype. Productivity and AI adoption deserve honest signals, not vanity charts.
-
Build for everyone
Accessibility was my first soapbox and it's still a default, not a feature flag.
