This course was a great match for me, especially because I work on UX/UI, web development, SEO, and Core Web Vitals optimization. The course provided practical insights into website performance, PageSpeed reports, and different techniques to make web applications faster and improve the overall user experience. I particularly found the performance optimization and PageSpeed analysis topics useful for my day-to-day work. The course helped me better understand how factors such as loading performance, JavaScript, images, CSS, and other resources can impact UX, SEO, and Core Web Vitals. Overall, it was a practical and relevant course that strengthened my understanding of web performance optimization and gave me useful knowledge that I can apply to real-world projects.

I think the instructor did an excellent job teaching the material. I especially appreciate how he walked us through a sample website which had various performance and accessibility issues and then instructed us how to resolve the issues with the help of tools like https://pagespeed.web.dev

Excelente curso, explica de forma muy clara de que se trata Web Core Vitals. Lo más importante del curso para mi, es que el profesor utiliza como ejemplo un desarrollo web sencillo que estaremos mejorando progresivamente para subir las estadisticas de experiencia de usuario, lo cual era justo lo que estaba buscando. Gracias!

This was a pretty neat course. It helped me look at a couple things, and influenced me to want to revisit some of my current practices. I still have a ways to go with learning this stuff. But this gave me some basic views and ideas to whether I was on the right or wrong track. Thanks

The course contains all the information I expected and hoped for. Ivan explains the material clearly, in an easy-to-understand and hands-on way. I recommend this course.
By Andrii Tomkiv on 6/4/2025
A quality course, simply and concisely explained. But there are few details for developers, such as which images should be lazy, which should not, how to work with optimization for video, etc., perhaps this was not planned.
By Trilok Vallamkonda on 5/12/2025
The course is well-suited for beginners, covering the basics effectively. However, it lacks depth and has very few examples. The content is heavily focused on image optimization, leaving many other important topics unexplored. More comprehensive coverage and additional examples would greatly enhance the learning experience.
By Ajith HP on 11/2/2024
The course was structured in a clear, step-by-step manner, making it easy to understand. I appreciated the detailed explanations and learned some new concepts along the way. It would be even better if the course included examples with dynamic data and APIs for a more hands-on experience.
By Winston Jade Molit on 9/9/2024
I learned a lot about web performance using HTML and CSS. I had many realizations after watching the course, as I realized I had been implementing things incorrectly when creating websites. This course has been very helpful to me. Thank you so much for sharing your knowledge.
