Why me

Field Data

I optimize from real user metrics (RUM), not only from Lighthouse scores. What matters is the experience of the person who is actually browsing and buying.

Performance as Revenue

LCP, INP, and CLS affect conversion, media efficiency, and retention. Performance belongs in the financial discussion.

High-Scale E-commerce

Experience with operations receiving millions of pageviews per month, where Black Friday is a real architecture test and milliseconds cost money.

This Site as a Reference

The site itself follows the same standard I recommend: SSG with Astro, edge deployment, and performance treated as daily practice.

“Well-managed performance improves experience, protects the operation, and helps the business sell more.”
