What I'm looking for

I seek a hands-on cybersecurity role focused on incident response, system hardening, IAM, and growth in a collaborative, security-first organization.

I am a Cybersecurity and Systems Analyst with hands-on experience supporting enterprise applications, administering Windows and Linux systems, and optimizing SQL Server databases. I have practical knowledge of the NIST Cybersecurity Framework and change management processes.

I have completed hands-on labs on Hack The Box, TryHackMe, and OverTheWire, and executed SOC-style investigations using Splunk to identify IOCs, correlate events, and produce incident reports. I have conducted vulnerability scans with Nmap and Nessus and performed end-to-end incident response aligned with NIST CSF.

I strengthened system security through security baselines, least privilege, MFA, Zero Trust, Active Directory and IAM administration while supporting users in helpdesk and banking environments. I am eager to apply my technical skills in a dynamic environment and take on increasing responsibilities to improve organizational security and operational excellence.
