Hi Pronaya Kumar S.,
I noticed your profile and promotion through a WP Youtuber. I would like to offer you my project.
We can discuss any details over chat?
Specifically, I have a good GTMetrix (currently A, Yslow B) but the Google Pagespeed Insights is only 54 for Desktop and an appalling 12 for Mobile. Can you optimise for Mobile and improve Desktop to >90? Is this something you can do?
