I initiated my first SSH session on August 12, 2013. Following that, I delved into Teamspeak³ server administration, handling extended permissions and Query commands. During my youth, I gained extensive experience with Minecraft server networks, particularly with the backend system "Bungeecord," as well as various cloud systems.

It wasn't until 2018 that I discovered my interest in Windows servers, Docker containers, and network technologies. Since then, I have continuously expanded my knowledge and skills. Currently, I am working at Netstack GmbH, where I further develop and apply my expertise daily.
