As a Cyber Defense Associate at one of Europe’s largest tech companies, I supported both offensive and defensive cybersecurity teams. I contributed to Bug Bounty, Penetration Testing, and Red Teaming efforts, as well as Cyber Threat Intelligence and Threat Hunting. I led penetration tests, discovered vulnerabilities in major cloud applications, developed automation solutions, and spent six months at our US headquarters.

In my role as a working student at a Cyber Security Operations Center, I audited Python code for SIEM detection rules and automated routine tasks using Python tools. I conducted malware analyses, investigated security incidents, and performed technical assessments. Additionally, I enhanced SOC processes by creating tools that aggregate and summarize data from various cyber threat intelligence sources.

As a working student, I administered users in Microsoft Active Directory and managed smartphones using VMware AirWatch. My responsibilities included maintaining switches and cabling, overseeing daily backup jobs, and performing computer and software installations with Microsoft SCCM. Additionally, I provided 1st and 2nd level support and coordinated Windows 10 and Office 365 rollouts.

During a one-year internship as part of technical secondary school, I provided 1st level support through a telephone hotline and documented issues in a helpdesk tool. My role included 2nd level on-site support, installing printers and software, troubleshooting, setting up and installing IT equipment, and inventorying IT equipment.
