Hi, I can definitely help you optimize your website load speed both for desktop and mobile. I will use various optimization techniques on frontend pages, admin end and also some in hosting panel to ensure it loads fast.
To make it above 90% on mobile especially it will need plenty of work and i will need support from you like in terms of optimized media etc.
I am a senior full-stack developer with 8+ years of experience with core skills in Php, WordPress websites, WordPress plugins development, APIs development, WordPress responsive themes, WordPress speed and performance optimization.
Let me know a good time to talk and we can take it further. I will make the final price after the initial discussions.
Regards
Imran
