What I'm looking for

I want to support system security assessments and compliance documentation, working hands-on with SIEM monitoring, vulnerability assessment, and alert triage—learning from strong teams while building reliable detection and remediation workflows.

I’m an entry-level cybersecurity analyst with hands-on experience in security monitoring, vulnerability assessment, and SIEM investigations across network and cloud environments.

I’ve built practical security capabilities through IAM and MFA work in a simulated financial platform, plus an Azure Sentinel brute-force detection simulation using PowerShell and KQL. These efforts strengthened threat detection and helped improve triage and investigation readiness.

In assessment and remediation work, I conducted a Windows security assessment of RDP access—reviewing TCP/IP configurations, firewall settings, and Microsoft Defender controls with Wireshark and Azure—and documented hardening recommendations. I also supported vulnerability management processes and continuous monitoring by collaborating with IT teams.

I bring additional depth from malware analysis and defensive training, including integrating VirusTotal API scanning and process analysis into a GUI dashboard for SOC-style triage. I also pursue secure software development through hands-on web attack lab work (like XSS) and incident-response-focused learning to support stronger security outcomes.
