Computer Systems Engineering student currently in the final stage of the degree, with two academic terms remaining.

I have a foundation in IT support and infrastructure, including Windows environments, network troubleshooting, and basic systems operations.

I am currently building hands-on experience in cloud security, systems hardening, and network security through Azure labs, Windows security practice, Linux administration, and Python-based security tools.

I am seeking internship and entry-level opportunities in cloud security, systems administration, or security operations, with a strong interest in banking and other regulated environments.

I am currently progressing through the IBM Cybersecurity Analyst path and preparing for Microsoft Azure Fundamentals (AZ-900) (exam pending).
