Improved page load
Improved site performance
Soon after Google announced that core web vitals is going to be a factor for SEO, me along with my fellow devs started working on improving site performance. 

A lot of them was focussed on 
  • optimising and converting images to webp format.
  • removing unused classes and scripts.
  • delaying certain scripts to load later
  • purge css
I learnt a lot about web performance on this task, and very thankful for the opportunity given to work on this issue. The community websites, such as smashing magazine, twitter community was all great and helped me a lot to complete this task successfully.
