I got a Master Degree in Computer Science at the University of Milan in 2003.
I have experience of work inside the FreeBSD kernel, particularly in the FreeBSD network stack: in 2005 i applied (and got chosen) at Summer of Code 2005, and had a chance to work on libalias and ipfw. As part of my research work, i spent the last months profiling FreeBSD's interrupt handling performance in 4.x and 7.x. From time to time, i like to profile different aspects of the FreeBSD kernel, in particular related to the network.
For my MS thesis, i wrote a firewall encapsulated inside a netgraph node, and just for fun i wrote a sort of bpf that let me manipulate network packets straight into the kernel.
