I'm a transplanted Canadian, who's been (legally) living and working in the U.S. since 1995. Most of my work experience has been within Information Technology, but my career has included brief stops in Operations, Warehousing and Marketing.
My favorite job was probably as Director of Marketng for a B2B (direct marketing) company, located in Toronto.
My most satisfying job was as CIO of a midwest manufacturing company, where my team standardized and regionalized international I.T. operations, then rolled out SAP worldwide.
Best lesson learned? It's not the technology, stupid. It's how well you use it.
