I'm a consultant working mainly with Atlassian tools such as JIRA and Confluence. I've written plugins, migrated data and configured large and small instances of JIRA over the past five years.
I'm also the author of Practical JIRA Administration and Practical JIRA Plugins, both from O'Reilly, 2011. I wrote Practical Development Environments (O'Reilly, 2005) to cover the other parts of a software toolsmith's job.
My contact details and more information are on my web page.
