Back to original languageAbout Dylan
Hello,
I help companies design, secure, and operate their IT infrastructures, from initial setup to daily operations.
As a Systems and Network Administrator, I design reliable and high-performance architectures tailored to your needs: hosting, virtualization, networking, monitoring, and automation.
I specialize in:
Deployment and management of infrastructures (VMs, dedicated servers, cloud)
Implementation of containerization solutions (Docker)
Monitoring and alert management (Zabbix, monitoring)
Performance optimization and high availability
System maintenance, updates, and security
My approach is simple: functional, stable solutions adapted to your environment, with an operations-oriented vision (not just theoretical).
