Summary of My Expertise

I am one of the foremost experts on VISTA and RPMS outside of VA and IHS. I have the unique distinction of having set-up multiple systems from the ground up. Today, I support VISTA and RPMS users.

My software

Historically, most software I have written is in MUMPS due to my involvement in VISTA and RPMS. In the same arena, I have written software in C#, Javascript/HTML, Delphi, Java and Python. Prior to getting involved in medical software, I wrote some stuff in ASP.net.

Today, I work on a C codebase and a lot of scripting around it.

These are some of the big open source projects that I worked on.

The summary of all this work can be found here.


A sizable collection of VISTA and RPMS set-up articles can be found on my page on Vistapedia.
