Hello, my name is Toshiaki Tanaka. I’m a Japanese university student majoring in medicine. Even though I don’t major in computer science, I occasionally play CTFs. For this I’ve used mitmproxy quite a bit, and so I applied to be a Google Summer of Code (GSoC) 2021 student for the project… and got accepted! In this post I would like to share my GSoC experience with future applicants.
