What I'm looking for

I am looking for a role that challenges me and allows for professional growth, particularly in system security and automation.

I am an experienced and skilled programmer with a strong background in reverse engineering, system security, networking, and virtualization. My journey in technology has equipped me with a diverse skill set that I am eager to leverage in a challenging role. I thrive on solving complex problems and continuously seek opportunities to enhance system performance through innovative solutions.

As a self-employed freelance developer, I have designed and implemented custom scripts in Python and Bash to automate repetitive tasks, significantly improving efficiency. My role as a Coverage Administrator at HLTV allowed me to implement and optimize anti-scraping measures, enhancing site security and protecting sensitive data. Additionally, my experience as a Site Reliability Engineer at FACEIT involved monitoring and optimizing Kubernetes clusters, where I developed comprehensive documentation for internal tools and processes.
