Recommend without hesitation.
I spent a lot of time trying to optimize my small biz site for speed. Desktop I was near 100 on PageSpeed Insights, but mobile/cell, I couldn't get past 36. Reached out to Lam and he worked his "magic" getting me to a mid-90's PageSpeed score in mobile. A huge improvement! Recommend without hesitation. Makes for a much better user experience on cell. Thanks Lam!
