Operating Systems and Computer Networks

During the years I worked with Linux, Windows and macOS systems. I have the most experience with Linux systems, but I also have experience with supervising Windows systems. I use macOS as my daily driver.

It is a huge topic, but I think it is important to mention that I have deep knowledge in the most important components of operating systems and computer networks:

• TCP/IP
• HTTP/s
• SSL/TLS
• DNS
• DHCP
• Email (SMTP, IMAP, POP3, SPF, DKIM, DMARC)
• Firewalls and NAT
• VPN
• VLAN
