Alexander Bluhm is an OpenBSD developer since 2007. His main area
of work is the network stack. In the recent years focus was on
multi processor performance. He is employed at genua, a German
firewall manufacturer, who is using OpenBSD an a secure and stable
base for its products. Other areas of interest are the errata
process, testing, maintaining Perl ports, and fixing all kinds of
bugs.

Andrew has been using OpenBSD for over 20 years and afresh1@openbsd.org for about ten now and in that time has nearly perfected his ability to slack. He primary keeps in the base system perl(1) up to date and maintains a few ports to have something to test those perl updates on. He hasn't used OpenBSD professionally since before he got his account, but continually wishes other things were as nice to use. He has also restarted and has been organizing the BSD Pizza Night in Portland, OR since 2014, shortly after moving there.

Andrew is a FreeBSD kernel hacker working on the Arm Architecture. He has been working on arm64 since the beginning, focusing on core architecture support.

Benedict works as a lab engineer at the University of Applied Sciences, Darmstadt in the database and operating systems group. He is teaching a class called "Unix for Developers" since 2012. Benedict is a documentation committer in the FreeBSD project and one of the moderators of the BSDNow.tv podcast.

I graduated from the Moscow State University, Physics department back in 2008 and joined Yandex as a network engineer the same year. Nowdays my non-formal job title at Yandex is a Network foreman (OKay, an engineer and a team lead) responsible for enterprise network in our offices, remote access and management network of our DCs. I manage a small team of network engineers to bring corporate networks to new locations on day-to-day basis, maintain solutions we've chosen to build, face new challenges and find a way to defeat them.

Born and raised in Austria, Chris studied Computer Science at the University of Technology in Vienna, Austria. He's been in IT since the late 90s and started working with FreeBSD around release 5. For the past 14 years he's worked in the construction industry in various IT management roles.

In 2021 he first became more active in the community by becoming a port maintainer and when Greg Wallace at the FreeBSD Foundation founded the Enterprise Working Group in 2023, he joined as volunteer. Since then, he's been an active contributor around bhyve and documentation, working on making FreeBSD even more useful and usable for enterprise use.

Dan Langille first started with Unix-like operating systems sometime in the early 1980s. In 1998, he discovered FreeBSD on a near-daily basis after needing a firewall for his ADSL connection. From that start, he began several online journals, founded two highly successful open source conferences, and eventually turned his hobby into a profession.

Dan now works as a sysadmin for a widely-known infosec company and is frequently impressed by those he works with.

When not running conferences or working, Dan blogs about this activities. He wishes he did more mountain biking.

Dave has spent the last 2 decades trying to stay at least 1 step ahead of The Bad Actors on the internet, starting off with OpenBSD 2.8, and the last 9 years with FreeBSD since 9.3, where he has a ports commit bit, and a prediliction for obscure functional programming languages that align with his enjoyment of distributed systems, & power tools with very sharp edges.

During this time, he has grown a set of private customizations including modifications to rc scripts and some kernel bits. After having worked for over 15 years in the CAD and finance sectors, he lately switched back to pure IT topics, and in particular operating system development.

He's currently a contractor for the FreeBSD Foundation, and a fresh (< 1 year) FreeBSD committer.

Patrick M. Hausen, born in 1968, developed an interest in all things Unix and networking in general in the late 80s. Having worked on various commercial implementations and looking for an operating system that would be more capable than Minix for actual daily use at home he found out about FreeBSD in 1993. He's been using, hacking, advocating and occasionally cursing FreeBSD ever since.

After working as a linux and OpenBSD system administrator for a few years, Patrick got back into web development and now works as a full stack freelancer. Though he still dabbles in system administration via devops.

He hails from the province of Québec in Canada and enjoys cooking, foraging and skiing.

Walter started hacking in the late 1980s, after he got his first UNIX account at his university. It was a time of pioneering. No computer crime laws existed but he was in some scary situations. Luckily, Walter was able to become an ethical hacker and make it his profession. He is also a known lockpicker and recently had a book published on the subject. When Walter is not hacking, he likes to read, sail, and manage his FreeBSD systems.

Warner has been involved in BSD and FreeBSD for a long time. Most recently, his work has focused on boot loaders, the storage stack and getting into trouble.
