I really enjoyed this course. In my job, I have to improve the performance of my application, and the truth is that with this course, I have learned the basics and the necessary strategies to take a step forward. Highly recommended. 🤩

Focus on the worst metric and perform the most basic fixes to improve your website's performance - that's the lesson I'm taking away. I learned a lot of cool and interesting stuff about web performance and realized how easy it can be to boost a website's performance exponentially. Great course! 10/10.
