Back to original languageAbout Richard
Looking for someone who understands your infrastructure in depth and sleeps soundly at night? That's been my job for 18 years.
Specializing in Linux/Debian, OpenBSD, and Proxmox, I handle everything from audits to 24/7 managed services for your critical systems. I've worked with Worldline, SFR Business, and Diabolocom, as well as numerous SMEs.
My areas of expertise include virtualization and cost reduction (Proxmox/Ceph migration), advanced networking (BGP/IPv6/VoIP - operating my own AS206014), security and PCI-DSS compliance, and high-availability multi-terabyte MySQL/MariaDB databases.
Entrepreneur since 2007, founder of RDEM Systems (2016). NTP Pool contributor since 2005.
