About This Website

This website allows me to use static web design and cloud technologies to build something practical.

In addition to being my personal website, this website is an experiment in basic web building techniques within a cloud environment. It is a static website which means that it uses the basic set of web building technologies. These include cloud hosting technologies, HTML, javascript, and current website technologies.
Wise people have told me that the only way to really learn the cloud is to use it and I believe this to be true. I have earned many certifications over the past few years. Using this knowledge is the best way to learn it. This website is hosted on AWS and uses many of the AWS technologies that were included in these certifications. Learn more...

Who am I?

If you are here you probably already know a little bit about me. But just in case you don't, here are the basics. I am a Cybersecurity Professional and a Programmer with over a decade of Graphic Design experience. It's an unusual combination, but I'm happy with it. Along the way, I have worked with many talented people and I have learned much.
