Hi, I’m zhiren, and I’m very passionate about technology.
I’m interested in mechatronics, computers, automotives, and all things engineering.
I’m curious, and likes to learn how things work under the hood.
I was also an active ctf player, mainly focusing on binary exploitation.
Nowadays, I’m spending most of my time building things and learning.

Projects

  • AES Messenger: Terminal messaging app that encrypts user messages using AES.
  • nand2tetris: Did an applied computer science course called nand2tetris, and built a computer from scratch.
