I spent the first part of my life in applications, traveling the world installing newspaper computer systems. I was one of many who interfaced between the software developers and end users, making things easier for people to use and maintain.
That evolved into web development, using HTML, CSS, JS, etc. to build websites and web presence.
Now with retirement, I keep finding new avenues to explore. As I do, I'll attempt to describe them -- on a level I hope folks can understand.
