About Me

I started with UNIX is 1993, using Solaris, and then moved to Linux in 1997 using Slackware, Red Hat, and now Ubuntu. I began Linux kernel development in 2001, in the USB subsystem, and have contributed since then in various kernel subsystems including memory management, networking, and crypto. I joined Canonical in 2015 as part of the Support and Technical Services Engineering team, and have been working on problems that reach into many different parts of Ubuntu; the kernel, networking, multipath, udev, iscsi, and more. I enjoy digging deep into technical details and solving problems.
