About the Author

Anna-Jayne Metcalfe
Founder Riverblade Limited
United Kingdom United Kingdom
I haven't always written software for a living. When I graduated from Surrey University in 1989, it was with an Electronic Engineering degree, but unfortunately that never really gave me the opportunity to do anything particularly interesting (with the possible exception of designing Darth Vader's Codpiece * for the UK Army in 1990).
    * Also known as the Standard Army Bootswitch. But that's another story...
Since the opportunity arose to lead a software team developing C++ software for Avionic Test Systems in 1996, I've not looked back. More recently I've been involved in the development of subsea acoustic navigation systems, digital TV broadcast systems, port security/tracking systems, and most recently software development tools with my own company, Riverblade Ltd.
 
One of my personal specialities is IDE plug-in development. ResOrg was my first attempt at a plug-in, but my day to day work is with Visual Lint, an interactive code analysis tool environment with works within the Visual Studio and Eclipse IDEs or on build servers.
 
I love lots of things, but particularly music, photography and anything connected with history or engineering. I despise ignorant, intolerant and obstructive people - and it shows...I can be a bolshy cow if you wind me up the wrong way...Laugh | :laugh:
 
I'm currently based 15 minutes walk from the beach in Bournemouth on the south coast of England. Since I moved here I've grown to love the place - even if it is full of grockles in Summer!
