About

I have a proven track record in creating novel technologies and architecting radical improvements. Among others, I introduced the first upstream open source hypervisor for the ARM architecture (Xen on ARM) to use hardware virtualization extensions, and lowered the boot time of Xen-based systems by 90%+ with Dom0less. I gave 50+ successful public presentations at technical conferences. I like to nurture and lead cross-company open source collaborations: I am currently working towards meeting stringent safety requirements for Xen on ARM, collaborating with vendors, such as ARM, EPAM, and Renesas.

Xen Maintainer and Committer

Feb 2012 – Present · 14 yrs 4 mos

Started the Xen on ARM effort in late 2011. During the following years, I grew a community around the project, and, together, we developed the code into a world-class hypervisor on par with its x86 counterpart. Today, I maintain the codebase, act as gatekeeper, and provide leadership for the Xen on ARM community.
