I love to write, and write quickly and clearly. I am a published writer and editor, with a PhD in math and years of experience as a programmer, system analyst, and consultant. I have written 8 books that span a variety of topics, from technology to organizational science to marriage. I've written hundreds of articles that cover a wide variety of topics in engineering and technology, as well as in other fields. I've also written technical manuals and "help" files for software products, and content for web sites. I'm fluent in English, Spanish, and Hebrew. I prefer fixed-price contracts, producing agreed-upon deliverables for an agreed-upon price to an agreed-upon deadline. But I can also accommodate hourly rate contracts upon request.
