I am sorry, but there is nothing partucularly impressive here as I only use GitHub for collaboration on projects hosted on the platform or if I plan on taking advantage of a rather generous GitHub Actions free tier for public repositories.
That said, I have one project here that you might find worthwhile - warcrime and it's accompanying warcrime-api.
If you are looking for more of my codes, please check out my GitLab.
I also invite you to take a look at my personal website. It features a list of projects that includes personal ones as well as volunteering contributions and some of my commercial work.
