As a serial entrepreneur and technologist, my 40 years in industry consumed me and investing was left to professionals. Most of my net worth was in the previous company I started when it went public in January 2000. A few months later, 90% of that paper wealth began evaporating as the tech bubble burst. After selling the business and retiring in 2003, time and interest allowed me to devote greater attention to investing and risk management. I spent the next 4 years developing a set of analytical tools to help me manage my investments. Those tools are now available to anyone at InvestEngines.com and are being used by other investors, financial analysts and wealth managers. I have advanced degrees in physics and electrical engineering and hold over 30 patents.
