The developer of the web sites in this domain had a long career as a mainframe computer programmer and software engineer. More recently he has obtained A+ (both OS and Hardware) and Network+ certifications from CompTIA. He has used personal computers for many years and run under many different operating systems: most versions of the Windows OS, Mac OS X and Linux (Ubuntu).
For the last several years, he has made many web sites running on free and purchased host servers and on his own home computer network using a variety of web server software packages. Many web design software tools and packages, both free and purchased, were used to construct these sites.
The developed web sites are a continuation of all of the web development efforts stated above.
