I dropped out of Uni without doing my master thesis and in later learned that if you need a US Visa a graduate degree is helpful, so in 2014 I went back to write a thesis (it was about satcom). I was getting a bit disillusioned with the project, and since I was running Linux on my Macbook air, and noticed that there was a Qemu GsoC project to make MacOS run without modification. Long story short, I got to RE the UEFI bootloader and find a bug in the Linux SATA code which landed me a job at a place that wanted to migrated from VMWare to KVM. I went on to do a fair share of performance work with SRIOV and DPDK, but unfortunately didn't really manage to continue working in that domain.
