Welcome to my GitHub profile! I'm a results-driven IAM Analyst and Senior Systems Analyst with deep expertise in Identity & Access Management (IAM), Cybersecurity, and Digital Forensics. I specialize in securing and administering Windows Server infrastructures, developing enterprise-grade automation scripts, and supporting high-availability IT operations.
I build robust PowerShell and VBScript tools to automate identity workflows, enforce ITSM compliance, and boost administrative productivity. My mission is to engineer secure, scalable, and reliable solutions that transform enterprise IT operations across public-sector and enterprise environments.
