I've moved about a bit, both geographically and occupationally. For the latter, I've worked on developer docs for products ranging from Visual Basic to COM to .NET to WebLogic Platform -- to name a few. I've also done some open source work along the way.
Expertise:
I've been working on technical content for a little over a dozen years. Mostly that's been developer documentation -- Visual Basic, COM+ (MTS 2.0), .NET, XML/XSLT/schema, and Java-based web services. On the teams I've been on, the focus has almost always been ease-of-use where the audience was relatively new to a technology. Sometimes that's meant trading off technical depth.
Pointers to stuff I've worked on:
