image Hi, I'm Lukas

I'm an aspiring Network Engineer from Czech Republic, now studying CCNA I -> Introduction to Networks at ČVUT.
I enjoy designing and building networks, and I like how each lab helps me understand networking more deeply.

image Goals

  • Finish all parts of the CCNA certification.
  • Improve my skills in network monitoring with Wireshark.
  • Build more advanced labs and projects in Packet Tracer and GNS3.
  • Get real-world skills for a future role as a Junior Network Engineer.

image Skills

  • Virtualization: VirtualBox, KVM, QEMU.
  • Lab tools: GNS3, Packet Tracer, Wireshark, VirtualBox, QEMU/KVM
  • Server Services: DHCP, DNS, HTTP (Apache2 / IIS), SSH
  • Monitoring: Wireshark, basic traffic analysis.
  • Operating systems: Windows 11 Pro, Xubuntu (KDE Plasma).
  • Documentation: Obsidian, Visual Studio Code.
  • Networking: Inter-VLAN routing, OSPF, static routing, ACL, DHCP, NAT/PAT, Port-security, STP, redundancy, GRE, NTP, Syslog, VLAN...

image Projects & Labs

I’m building a portfolio of projects in Packet Tracer and GNS3. These projects show my path from simple labs to more complex networks.
👉 You can find all my projects and labs in the repositories section.
