What I'm looking for

I seek a dynamic role in cybersecurity where I can leverage my skills and contribute to protecting organizations from cyber threats while continuing to grow professionally.

I am a dedicated Cybersecurity Engineer with a robust foundation in Network Security, SOC operations, and Penetration Testing. My journey in cybersecurity has been enriched by hands-on experience through four internships, where I developed practical skills and a proven track record of solving CTF challenges across various platforms. I am passionate about protecting organizations from advanced cyber threats and eager to apply my expertise in a dynamic role.

Currently, I serve as a Cybersecurity Instructor at GOMYCODE, where I teach and mentor students in preparation for the CompTIA Security+ certification exam. I lead hands-on labs using tools like Nmap, Nessus, and Metasploit, helping students develop practical cybersecurity skills. My commitment to education is matched by my technical acumen, having created and delivered course materials that align with the latest industry standards.

Throughout my internships, I have gained valuable experience in various aspects of cybersecurity, including implementing detection mechanisms, conducting penetration tests, and developing AI models for threat classification. My academic projects, such as designing a Next-Gen SOC architecture for healthcare organizations, have further honed my skills in creating robust security solutions. I am excited to bring my knowledge and passion for cybersecurity to a forward-thinking organization.
