TostaRica (2025) — Nuxt 3
Problem
Campaign traffic spikes; keep TTFB low and scale without downtime.
Decisions
- Nuxt 3 + ISR for critical routes
- Responsive images and CDN edge caching
- Pre-render high-traffic landing pages
Architecture
- Nuxt 3 + TypeScript
- Edge caching, route-level code splitting, CI/CD
Results (numbers)
- 500k+ monthly visitors, 0 downtime
- LCP ~1.8–2.4s
- CLS < 0.1
My role
Frontend lead (performance budget, audits, pipeline).
