About the Author
Bill Lubanovic has developed software with Unix since 1977, GUIs since 1981, databases since 1990, and the Web since 1993.
In 1982, at a startup named Intran, he developed MetaForm, one of the first commercial GUIs (before the Mac or Windows), on one of the first graphic workstations. In the early 1990s, while at Northwest Airlines, he wrote a graphic yield management system that generated millions of dollars in revenue; established a presence for the company on the Internet; and wrote its first Internet marketing test. Later, he cofounded an ISP (Tela) in 1994, and a web development company (Mad Scheme) in 1999.
Recently, he developed core services and distributed systems with a remote team for a Manhattan startup. Currently, he’s integrating OpenStack services for a supercomputer company.
Bill enjoys life in Minnesota with his wonderful wife Mary, children Tom and Karin, and cats Inga, Chester, and Lucy.
