Systems Administration

From Windows to Linux, macOS to even FreeBSD, I’m your guy to manage your systems and keep your infrastructure up and running with high-availability and security best-practices. I take the time to design firewall rules to exactly match a business’s requirements, and I keep systems up to date, utilizing central update management where possible. Systems administration is something natural to me, and I would love to do it for your company.

Systems I’ve Worked With:

1. FreeBSD

   • I like to use this in a NAS, for VPNs and anything network-heavy due to its excellent TCP/IP stack.

2. Ubuntu

   • Good default choice for Linux due to its fairly ubiquitous support from many vendors. If Linux is supported, chances are it supports Ubuntu.
   • Great choice for developers who want to work in a similar environment to deployment, without some of the drawbacks of the lesser-supported distros.
   • Also my daily driver

3. macOS

   • Great choice for content creation. Apple has always catered to them, and it shows in many ways.
   • Great choice for education
   • Great choice for developers who want a better-supported operating system than Ubuntu, but an environment that is at least similar to the environment where their code will likely be deployed (some Linux distro).

4. Fedora

   • Great choice for those brave few who want a highly-secure operating system, and are willing to sacrifice some stability and possibly security for the latest features.

5. openSUSE

   • Great general-purpose operating system, but not well-supported by the industry.
   • Great package manager with a fairly user-friendly CLI-based user interface built-in, which is pretty unique.

6. RHEL

   • For those who want the most security currently available in a Linux distribution, this is the one for them.
   • Comes with SELinux, which is the source of its strong security.
   • Also for those willing to pay for enterprise support

7. CentOS

   • Basically the same as RHEL, but for those who don’t want to pay for RHEL’s enterprise support

8. Windows 10/11

   • Best choice for gaming!
   • Best choice for environments where the systems need to be tightly locked-down, thanks to Active Directory, BitLocker, among other things.
   • Thanks to Microsoft’s Office suite, great for productivity. Its history of major security and reliability issues in the past does detract from this a good bit, though.

9. Windows Server 2008R2/2012/2012 R2/2016/2019/2022

   • Best choice for those who want active directory provided by the maintainer (Microsoft)
   • Best choice for those who want SQL Server, hosted on a Microsoft platform, although Linux is an option today.

10. VMware ESXi/vSphere

    • Virtualization. They do it well. Broadcom is concerning, however.

As you can probably guess, my favorite platform is GNU/Linux, but I’m not limited to any specific platform, and welcome experience with any of them. I’m well-aware of the general best use-cases of each OS, and I try to deploy them only where most appropriate. Systems administration is something I know well, and I love to try new things.
