Developer logs in to http://wikitech.wikimedia.org and can define the organization she works for (e.g. WMF) and her location (e.g. San Francisco). She can also identify different handlers she is using in Gerrit, Bugzilla, Wikimedia mailing lists, etc. All this information is then synced with ouur automated community metrics at http://korma.wmflabs.org/
http://wikitech.wikimedia.org usernames are connected to Gerrit usernames, which is a good theoretical backbone to connect with other usernames in other developer tools e.g. Bugzilla.
This is also potentially a good basis to gather more user data to improve our community metrics reports at http://korma.wmflabs.org e.g. organization and location of the contributors willing to share this information.
This would also be a preliminary step to the display of personal statistics in user profiles - now available in a first incarnation at e.g. http://korma.wmflabs.org/browser/people.html?id=151&name=Jeroen%20De%20Dauw
