A Brief Introduction to Tiexin Guo

Hello world, and this is Tiexin Guo. I’m a software engineer.

I had been working in the EU for the past five years, but I relocated back to China in mid-2021. Currently, I live in Chengdu (and/or Kunming), but I prefer to think of myself as a citizen of the world.
