Lately I have seen posts where individuals have re-submitted their Express Entry profile and received PT Notifications within weeks.

I am wondering whether or not I should do the same. ???
Please share your thoughts on this.
My current CRS is 440, I have a Masters Degree verified by an ECA (WES), over 15 years of working experience in my home country, my IELTS scores are: L(8.5) R(7.0) W(7.5) S(8.0) and my NOC is 2171 though I could change it to 2174 because I also develop web applications.
