About Me

I'm a passionate cybersecurity enthusiast and system administrator with a strong focus on technology and innovation. Currently pursuing my Master's degree while working in technical support, I dedicate my spare time to penetration testing, system administration, and DevOps practices.

I manage both public and private VPS environments, handling everything from server configurations to security implementations. My bachelor's thesis involved developing penetration testing tools, which I plan to make publicly available to help the cybersecurity community.

With over 5320 successfully resolved tickets and 1900+ hours of hands-on server experience, I bring both theoretical knowledge and practical expertise to every project.
