My real name is Long. I am from Vietnam.
My codename (pun intended) is Kira Zero, aka kirazero17. kirazero17 is also the my main GitHub username.
Obsidian 24 is the name of my tech blogging project, which include this site and a few other documentations that will come to be. You can find the source code of my blogs in the GitHub organisation LongKira-Obsidian24, which you won’t be editing but cool to see.
My brief history
I was the college student whose major was Computer Network. With a lot happened, I came across Cloud Computing platforms, System Administration, CI/CD, Containerisation & Container Orchestration, Software-Defined Networking, Low-level programming, and Reverse engineering. The last two are more like hobbies than something related to my career. Over time, I realise that I can’t just remember everything, so, documenting stuffs that I would re-read later on or share with others seems like a more reasonable choice than keeping it all to meself.
