Cybersecurity engineer in enterprise defense and cloud — turning signals into actionable intelligence. Now applying cloud and generative AI to enterprise defense.

About
Security is a system, not a stack of tools. I've protected 1,000+ endpoint environments and seen how single policy misconfigurations cascade across entire fleets.
I'm curious how systems fit together — infrastructure, threats, and now the AI entering enterprise environments. Cloud and agentic AI are the next layer of what I already secure. I build systems that are genuinely useful with safeguards to catch abuse. I don't just fix what's broken — I understand why it broke.
Experience
Cybersecurity Engineer
Lead endpoint protection for 1,000+ devices — owning EDR, vulnerability management, and threat-intelligence correlation across enterprise and cloud. Spearheaded an AI-driven email-security deployment and turned firewall telemetry into network-segmentation decisions.
Technical Support Engineer II
Performed system administration duties — managing endpoint security to deploy VPN and enforce policy, configuring SSO with SAML and conditional access, automating user management and reporting, and maintaining Windows server infrastructure and Active Directory. Provided advanced technical support and mentored junior team members.
Technical Support Engineer I
Owned end-to-end support across Windows, macOS, iOS, and Android while taking on growing systems administration — managing OS updates, application deployments, and SSO administration as subject-matter expert for a leading mobile device management solution.
Microsoft 365 Technical Support Specialist
Expert support for Microsoft 365, resolving complex customer issues and managing installation, configuration, and user/license provisioning across platforms. Documented work in a ticketing system and escalated product bugs.
Information Technology Technician
IT support for NYC clients — deployment and maintenance of Windows and Office 365 environments, Active Directory / Azure AD administration, SOHO network setup, and end-user training.
Building Toward
AI makes decisions inside organizations using security frameworks that don't exist yet. I'm building cloud-native defenses for AI systems and using AI to accelerate security operations — better analyst tools, not replacement judgment.
Agentic AI shifts security from deterministic code to natural-language instruction. The challenges: scoping agent knowledge, secure credential handling, domain isolation, and constraining systems that interpret rather than execute. My defensive work is grounded in offensive experience — red-team skills through structured penetration-testing labs, while pursuing CISSP certification. Understanding actual attack vectors makes defensive architecture meaningful.
