My investment portfolio is mostly stock options from the companies that I have worked for. I buy small amounts of companies that I like and I do well enough to say that I make more money than I lose. My technical expertise is in the odd netherworld between computer science, biotechnology, and chemistry. I have six patents and several products that I have worked on currently in the marketplace. I am working on closing down my full-time work life, but I figure that I will be bored to tears without something to do, so I will be spending a lot more time here on Seeking Alpha, trying to figure out which way the tech world will roll.
