Projects

Threat Intelligence Log Analyzer

Sep 2026 to Present

Threat Intelligence Log Analyzer generates simulated enterprise authentication and network event logs with attack patterns deliberately injected, including brute-force attempts, privilege escalation, lateral movement, and after-hours access. Four SQL detection rules (using GROUP BY, HAVING, and aggregation) run against the log data, persist structured findings to a SQLite database, and produce a severity-ranked threat report covering total findings, severity distribution, top flagged users, and critical alerts.

IT & Network Infrastructure Lab

Jan 2026 to Present

A VirtualBox home lab running Windows 11 and Ubuntu VMs, built to practice enterprise network administration and IT support end-to-end. On the infrastructure side: VLAN segmentation, firewall rule configuration, and inter-VLAN routing to simulate production network architecture, plus access control lists, endpoint hardening, and backup integrity verification for simulated NAS storage. On the support side: a Microsoft 365 developer tenant configured for account provisioning, conditional access/MFA policies, and SharePoint administration, with the full change and ticket lifecycle documented in a ServiceNow developer instance.

AV & Hybrid Event Systems

Aug 2025 to Jun 2026

A hybrid A/V test environment built with Zoom and OBS to practice multi-source stream routing and audio mixing, using the same technical stack as production hybrid event support. That experience carried directly into producing and running in-person cybersecurity workshops and speaker events as Vice President of ISACA NY Metro Chapter's Yeshiva University student group, handling A/V setup and teardown, projector and display systems, livestream support, and event troubleshooting for 5+ events a semester.
