Welcome!

However you found this site, I am happy you are here. Most of what you will find here is things that I have learned or observed. In the Leadership section you will also find some of my thoughts on leading others OR leading yourself. My tech writing is here to share solutions to problems I have had to solve. I post here to help others avoid some of the mistakes I have made (and to have notes for myself so I can avoid repeating mistakes).

This site is built on an open source framework called ChassisPHP, a project that I lead. Check out the project on Github - ChassisPHP  For my non-tech visitors, a web framework is a foundation for a site. It manages things like directing page requests to the correct files, the database connections, security, etc.

To find out more about me, check out the links in the footer. There are links to most of my public internet presence.

Thanks for visiting, and I hope you learn something and will come back.
