Writing in Python, for Python, and about Python to automate everything under the sun.
About Me
Currently an Automation Engineer @ Meta.
Python fanatic obsessed with turning computers into perpetual workers that do everything for us as much as they possibly can.
In my spare time, I write about Python on Medium (zlliu.medium.com) and Substack (zlliu.substack.com) , and develop PyPI projects for fun (https://github.com/zlliu246)
In my spare spare time, I boulder, badminton, beatbox, cook, eat, exercise, read, game, play music, and hang out with the people around me.
