Principal Software Engineer & Founder

Phillip Gourley

I build platform foundations that scale — and now I'm building my own. 15+ years spanning edge architecture, Core Web Vitals, SSR infrastructure, and developer ecosystems. Currently founder of webvitals.sh, bringing performance monitoring to engineering teams. From re-architecting platforms for IPO readiness to driving 6.5× faster global performance, I work at the intersection of deep technical craft and organisational leadership.
