Remember, any developer can deliver product as per your need, even a student. But when it comes about efficiency then most opts out. I am a full stack nodejs developer having 7 years of industry experience, and can deliver the solutions with low latency and more than 90% of w3c compiled web & apps. And ofcourse, cross-browser optimized & full responsive with maximum devices compatibility worldwide. Maximum visitors opts out browsing any website if it takes more then 10 seconds to load, so i personally focus on these sections, which works on really very poor networks. This really matters, and it can't b avoided.
