Evtim Batchev is a CTO at Halian. He possess expertise in security, data center, solaris, virtualization, unix and 42 more skills. He is proficient in Russian, Catellano and English. Colleagues describe him as "Efi's a very original thinker, and has an uncanny knack of coming up with ways to break system security - as other commenters have remarked, it's as well he chooses to work for those on the right side of the law :-). Recently, he's developed a particular interest in forensic analysis of Solaris systems which have been compromised; he's been building an analysis framework based on kernel runtime invariants, which shows a particular deep understanding of How The Kernel Works, as well as forensic analysis and evidential data handling. It's quite remarkable that he manages to hack so diligently on this stuff, and still remain as laid-back as he is." and "Efi is a really GREAT person to work with, a very smart technical person and a very friendly colleague. Hope to work with you again soon !"
