I've been running a blog at https://xeiaso.net for almost a decade now. It has been the single best decision I have ever made in my career. It allows me to skip technical screening interviews. It has made interviewing at companies _easy_ because I have _already proven_ that I understand what I'm talking about.

Learning how to write well also makes it so much easier to explain things succinctly, especially when working remote like I prefer to.

I've also been told that more junior people look up to me as a role model because of my blog, which is something that I am still getting used to, but I can accept.
