Integrated PentAGI as an autonomous multi-agent penetration testing platform driven by a self-hosted Ollama instance running on a Windows desktop, with a Raspberry Pi 5 acting as the PentAGI host. Azure subscription policy conflicts required full migration to complete self-host using VirtualBox. ### GCP Virtual SOC Lab (VISI Workshop Infrastructure) Built a prior iteration of the vSOC lab on Google Cloud Platform using custom VMs and OpenVAS / Greenbone running on Kali Linux in VirtualBox. Prepared per-student VMs for hands-on workshops. Resolved persistent OpenVAS feed update failures traced to slow read/write drives. ### Homelab Operated a Raspberry Pi 5 homelab running Kali Linux with static IP configuration, AdGuard Home for DNS filtering, Samba file sharing, MiniDLNA media streaming, and TightVNC for remote access (cut for security). Paired with a Proxmox-based HP EliteDesk 800 hypervisor. Currently offline due to hardware defects. ### Inventory Scanner Application Developed a local React Native + Node.js application that scans 1D barcodes and writes entries to CSV. Designed for offline use and simple deployment on Windows or Linux hardware. ### Gulf of Mexico Water Quality Analysis Dashboard Built a local web application that analyzes Gulf of Mexico water-quality datasets with AI-assisted characteristic matching and basic charting, originally produced for an admission application. --- ## Leadership & Outreach ### Lead, Vaquero Information Security Initiative (VISI) **University of Texas Rio Grande Valley** | Active Lead and active member of VISI, a student-run cybersecurity organization working toward formal cyber clinic status to serve under-resourced organizations in the Rio Grande Valley. Responsible for organizing technical workshops, mentoring members, and coordinating outreach. Organization site: https://vaqueroisi.org #### Vulnerability Management Workshop Delivered a hands-on workshop covering port scanning and vulnerability assessment with NMAP, AngryIPScanner, and OpenVAS. Explained the CVE system, zero-day vulnerabilities, IP addressing and subnetting, SQL injection, and path traversal. Distributed a preconfigured Kali VirtualBox VM with OpenVAS installed to attendees. #### OSINT Tools Workshop Demonstrated open-source intelligence techniques across identity, infrastructure, and incident response domains. Coverage included username enumeration, facial recognition search, metadata and geolocation extraction, domain email enumeration, Google dorking, IP and port reconnaissance, data breach verification, people / property / vehicle lookup, surveillance awareness, malware hash analysis, browser-based sandboxing, phishing email analysis, and subdomain enumeration. --- ## Key Achievements - Dean's List recognition across multiple semesters at UTRGV. - Letter of recommendation from the CISO of Cameron County IT. - Designed and deployed a functioning Azure-based virtual SOC and AI-driven pentesting lab as a personal research initiative.
