Good day!
I have two decades of hands-on experience in designing, installing, maintaining and optimizing a wide variety of secure Internet servers: web servers, e-mail servers, DNS servers, IRC servers, VOiP servers...
The #1 platform I like to work with is OpenBSD, but I can fully manage with any Linux distribution as well. I also have experience of the enterprise level systems, including Solaris and OmniOS.
Nginx, MariaDB / MySQL, Postfix, Dovecot, Squid, WordPress -- you name it, I've probably already worked with it.
Optimizing web server performance is one of the things I really love! Is your Apache based site getting slow under heavy use? I already know how to give it performance boost of at least 30% -- probably much more.
Hardening Windows security is one of the areas I've delved particularly deep for a long time. Are you having issues with break-ins, or do you want to enhance the security of your systems proactively? I have "agent level" solutions for you.
Let's talk!
