I have been CEO, CTO, COB, VP Engineering, Board member, advisor to numerous companies. I have been in companies during 2 public offerings, 2 sales of companies to other companies.
I invented publish/subscribe and have 10+ patents in messaging, security, content management, file systems. I was a founder of TIBCO and several companies, been on advisory or other boards. My new passion is what I call Platform 3.0 and what I believe is the network effect of the cloud and IoT that will transform our lives. Read my blog to get insight on what that means.
