''Tell us a bit about yourself.'' 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.

''Tell us how you got involved, what you liked working on and what you could probably do better.'' 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, and more. I enjoy digging deep into technical details and solving problems.

Who I am

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.

My Ubuntu story

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, and more. I enjoy digging deep into technical details and solving problems.

Areas of work

Most of my work is done in the kernel, both upstream and in Ubuntu's branches. However, I also make fixes to various packages as I, or Canonical customers or public Ubuntu users, find bugs in them that I am in a position to fix.

Things I could do better

Time management is difficult for everyone, as we never have enough time to complete everything we want to do. I hope to manage my time better, balancing work and family while also continuing to contribute upstream.

Plans for the future

Keep improving Ubuntu and Linux in general!

What I like least in Ubuntu

Documentation is sometimes hard to come by, or out of date.
