The Vue.js/Nuxt Ecosystem I Master

Vue 3 & the Composition API: Modern by Design

Vue 3’s Composition API is the standard in 2025. I use it to craft modular, maintainable solutions that scale.

Key strengths I bring:

  • Suspense to handle async loading gracefully
  • Teleport for refined modal and overlay UX

Nuxt 3: My Full-Stack Sweet Spot

Nuxt 3 has redefined full-stack Vue development, and I understand all its subtleties. It’s no longer just a front-end tool—it’s a complete web application platform.

Nuxt 3 Capabilities I Leverage

  • SEO-ready SSR tuned for speed
