Hi there!
Sure thing. I basically was playing with an RPC framework to make my old company project fast in 2017 see github.com/smfrpc/smf
I wanted to play with dpdk then.
When I started this in 2019 I wanted to use a framework that was battle tested, so seastar.io fit the bill.
There is also a big part of it that I had been professionally programming in c++ for many many years.
Last, this evolved from a prototype on my laptop in miami to company.
I think rust would he am excellent choice as well and I bet we'll write a bunch of rust in the not too distant future.
