Hi! I'm a professional software engineer who works full-time in open-source, so I'm no longer in any need of donations.
My most popular project to date is Lark, a parsing library for Python: https://github.com/lark-parser/lark/
You can see the rest of my projects here: https://github.com/erezsh
I also maintain a blog that had a few popular articles over the years: http://blog.erezsh.com/
