Charalampos (Babis) Mainas is a systems engineer at Nubificus and he is mostly interested in the lower levels of the systems stack, mainly in Hypervisor and OS level, where he enjoys to create kernel Oops. A significant part of his time has been spent in Unikernels, porting applications, libraries, language runtimes and in general trying to make them more friendly in existing technologies. Moreover, he had the chance to dive in the 2 most well used hypervisors (KVM, Xen). Lately, he started exploring the area of hardware acceleration, in order to provide an efficient and secure virtualization solution for devices (GPUs, FPGAs). He graduated from School of Electrical and Computer Engineering in National Technical University of Athens (NTUA). During his thesis, he designed and implemented a fork and pipe mechanism for Unikernels, preserving their single address space notion.
