Internet sleuthing leads me to believe he works at AWS as a senior program manager.

We have four Amazon services on the front page of HN at time of posting, and another three on page 2. Prolific week for Amazon, or is this a targeted campaign?

Considering this account and the event going on, I'd say it is a mix of both.

AWS re:invent is going on which explains why a lot of amazon postings are on the site. It's their yearly conference where they announce all their new features

That explains why there are a lot of Amazon postings on the site, not why the mentioned account is exclusively used to promote Amazon announcements.

I agree I was simply responding to the question of why so many are there today. Definitely legit to question that particular accounts history.

Their conference is on as we speak so, the former?
