Hi hun, you only want to be doing PUPD or ssh/pat if he is upset crying, otherwise leave him to it. If he is waking at 30mins I would try W2S around 20mins and stay with him if you can to see what happens and maybe hold him through the jolts if you can catch him as he's transitioning. How old is he? Do you want to post your day in EAS format so we can take a look?
