I have been in a technology role for more than 20 years now. Started off working at Sun Microsystems back in 1996 as an entry level systems administrator. I have worked for companies like Netscape, Tivoli Systems, Amazon, Cisco Systems and most recently IBM.

My expertise has been in Linux, Windows, Network, Virtualization and most recently in Cloud Computing. 




I have a bachelor's degree in Electrical Engineering from Wichita State University.

I have previously taught courses at community colleges and have taken technical training online. 

I think I can explain technical subjects in a very systematic and easy to follow manner.
