I write add-ins to Microsoft Office. You can see my work at Great Circle Learning. Some of the add-ins I have written are free, the AuthorTec line of tools, I do that as part of my community support efforts as a Microsoft MVP.
In addition to being a software designer and developer, I am also an instructional designer and developer. That is why you will see many, but not all, of our products and services targeted to the Learning and Education industry.
