Core Web Vitals sits in the Frontend layer of the stack.

Six years of frontend architecture, most of it on surfaces other people depend on daily. React and Next.js for composition and the full-stack picture. Angular in production at Capital One — reactive forms, lazy modules, a Karma-to-Vitest migration. Module Federation and micro frontends as an organizational tool, not a buzzword. Core Web Vitals and WCAG 2.2 because a page nobody can load or read is not shipped.
