About Richard

Virtualization engineer with over 6 years of experience in designing, installing, and managing VMware environments. Expertise in optimizing infrastructures for high availability and performance.

With 8 years of experience in Linux operating systems, primarily RHEL and CentOS, with in-depth skills in advanced administration, update management, system troubleshooting, and performance optimization.

My expertise in managing modernization projects has been demonstrated through the successful completion of major operations such as storage array migration, network core switch replacement, and script optimization for failover to a secondary site, each time generating measurable performance gains and a notable reduction in operational risks.

Constant curiosity for the evolution of IT infrastructure technologies, and a proactive approach to optimizing the resilience and performance of IT environments. Autonomous and independent, I am also capable of working in a team and sharing my knowledge.
