experience
security operations intern / Dartmouth ITC
- Triaged external vulnerability scan results through host identification and exploitation-likelihood confirmation, prioritizing remediation using KEV status and EPSS scoring
- Leveraged OSINT platforms (Shodan, Censys, GreyNoise) to surface externally-visible exposures and contextualize scan findings against real-world scanner activity
- Navigated Splunk and CrowdStrike dashboards to analyze endpoint, identity, and network telemetry, applying established playbooks and surfacing anomalies for senior analyst review
- Investigated phishing, malware, and anomalous identity events end-to-end on assigned alerts, pivoting across log sources to scope impact and recommend containment
- Supported threat actor and campaign attribution during active incident response, mapping observed TTPs against MITRE ATT&CK and known threat groups to inform containment scope
service desk technician / Dartmouth ITC, Client Technology & Consulting
- Delivered in-person technical support across Windows, macOS, and Linux systems for students, faculty, and staff, spanning BYOD and organization-provisioned devices
- Triaged and resolved client requests through TeamDynamix ticketing under established SLAs, escalating complex cases to senior technicians as appropriate
instructor / Code Ninjas
- Taught foundational programming concepts (JavaScript, Unity/C#, Roblox/Luau) to 150+ students in grades K–11 and mentored teens on game development projects.
- Maintained and secured a fleet of 20+ student computers, including imaging, updates, and routine troubleshooting.
- Reduced recurring endpoint issues by improving device management and implementing OpenEDR visibility.
- Adapted curriculum and instructional strategies for neurodivergent learners; built strong rapport through structured, digital-native engagement.
projects
Personal Homelab & Secure Network Infrastructure
- Designed a persistent home-server environment using a hardened Windows host with out-of-band KVM and Tailscale for remote recovery and administration.
- Deployed Ubuntu Server–based infrastructure to run application services, automated task runners, backup pipelines, and containerized workloads.
- Implemented observability practices with log aggregation, uptime checks, and health monitoring to ensure service reliability.
- Applied least-privilege credential management, firewall hardening, and network segmentation across development, administrative, and media services.
Experimental Phonetics Research – Lakota Speech Analysis
- Analyzed acoustic speech data using Python and Praat, building scripts to process and compare voice onset time measurements across tokens and speakers.
Research Assistant – Speech Surrogacy
- Document a corpus of U.S. military boatswain’s whistle and bugle signals, align it with a speech-surrogacy framework, and analyze system and signal structure for linguistic features.
certifications & honors
- GIAC Security Essentials (GSEC)
- GIAC Foundational Cybersecurity Technologies (GFACT)
- CompTIA Network+
- SANS Advisory Board member
- National Cyber League, Spring 2025 — Individual Game: 99th Percentile (20th Place, HS Bracket)
leadership & activities
Junior Reserve Officers’ Training Corps / NV-20121
- Directed daily operations for a wing of 120+ cadets, overseeing training schedules, personnel accountability, readiness, and standards compliance.
- Managed a leadership team of flight, group, and wing-level cadet leaders; coordinated delegation, performance tracking, and conflict resolution processes among a headcount of 30+ individuals.
- Planned and executed large-scale community engagement events, including 1500+ cumulative service hours per year.
