Since September 2012, I've been the network administrator in my school.
It's a big network to manage, extended across 2 buildings and with more than 1000 users.
It is fully covered by a wifi network and provides a lot of different services to our users.
Truly fun! (for those who like it...)
In 2008, I initiated the rekonq project, developing a web browser based on WebKit and well integrated with the KDE workspace.
I'm sorry to say I'm unable to maintain and develop it now, cause of work and life things :(
