Good to "hear" from you again @steemchiller.

"Since I'm heavily working on the new backend, there is currently not much to tell about my recent developments."

Certainly not a problem for me, as I know whatever it is, it will be good. Oh, wait a minute! You have provided us with a bulleted list, most of which I have some idea about, but not in detail. Except this one:

Yes, that sounds wonderful, as I don't think one can go faster than light, so you would've reach the pinnacle of success! 😉 👌

Seriously, I do hope you are getting sufficient rest and staying in good health. Until next time, all the best to you! 👍
