Experience
2023 - Present
                Junior Penetration Tester & Security Engineer at SmartTECS Cyber Security
                
                    As part of my role, I was responsible for conducting comprehensive penetration tests across various environments, developing robust IT emergency response plans, and supporting the implementation of ISO 27001-compliant information security management systems. I also designed and hardened Linux-based infrastructures (RHEL and Debian) and integrated as well as monitored network detection systems, including NIDS, AIDS, and HIDS, to enhance overall organizational security posture. I was actively involved in threat intelligence gathering and analysis to proactively identify, assess, and mitigate emerging risks.
