Hi, the author is here

I am working in MapReduce/Data-pipelining/Dataproc efficiency internally and externally. In cloud you can check out Google Cloud Dataflow

We are working closely with general efficiency and bare metal teams, yes :). They definitely do a fascinating work. This one was my 20% project together with the google efficiency team

I'm not sure if you're asking me personally or about the original post, but to be clear: I'm not (currently) associated with Google, nor is my work on pdqsort or glidesort. I'm also not associated with the original post, other than that my work on pdqsort was credited at the bottom of the blog post, which is what my opening sentence was referring to.

I edited my comment to reflect this, I can see how it could've been misinterpreted. It was not my intention to deceive.
