As we delved into the project, our focus shifted to the AutoZone web app, already in development for two years with unsatisfactory performance. Recognizing the client's goal to improve web performance and SEO rankings on Google, we geared our efforts to help them achieve the desired results.

Working closely with the client's SEO team, we focused on Core Web Vitals metrics, including:
- Time To Interactive,
- Largest Contentful Paint,
- First Contentful Paint,
- Cumulative Layout Shift with Time To First Byte

Continuous monitoring with Lighthouse resulted in:
