Background

• https://github.com/hychan48/google-foobar-2023-q4
• I searched proxy vs load balancer. and at first I found it mad sketch
• had to verify it's SSL/TLS cert and Google was foobar was.

Assumptions

• So far it looks like it's either Python 2.7 or Java 8
• I'm going to use Python 3.11.6, using basic syntax it should be backwards compatible with 2.7
  • Also, I have PyCharm installed already
• TDD with PyTest
