My name is Petar, and I offer lessons in computer networks and network security for pupils and students.

I have 3 years of professional experience as a Network Security Engineer, and I hold a Bachelor’s degree in "Cybersecurity" from the Nikola Yonkov Vaptsarov Naval Academy.

In addition, over the past few years, I have successfully obtained the following certifications:

CCNA, CKA, Palo Alto, JNCIA, NSE FCSS

During the lessons, I will focus on the practical application of knowledge. I aim to combine theory with hands-on exercises, which can be practised using various simulators such as Cisco Packet Tracer and GNS3. The knowledge will be reinforced by solving real-world problems that may arise in the field of computer networks.

The lessons are intended for pupils, students, and anyone interested in the field of computer networks.
