I've working to improve website's Performance and Core Web Vitals using a set of different tools and technologies to prototype, improve and monitor performance.
On a daily basis I use tools like Webpagetest, Lighthouse, Chrome Devtools, analytics, Google Search Console, CrUX (Chrome UX Report).
Based on the analysis I can get from these tools I try to use all features possible from ReactJS (still testing the new concurrent features), NextJS, CloudFront and the Browser capabilities themselves to get my website to the best performance possible.
