About
I'm a Computer Science student at George Mason University, graduating in May 2027, with a focus on software engineering and cybersecurity. I hold the CompTIA Security+ certification and am a Certified Palantir Foundry Aware Professional, with hands-on experience in enterprise data pipelines, AI-driven workflows, and application development on the Foundry platform.
Outside of academics, I serve as President of my club hockey team, managing a $75,000 budget and a roster of 20+ athletes and staff. I am also an Eagle Scout, a distinction that reflects my commitment to leadership, community service, and personal accountability.
Actively seeking internships in software engineering, cybersecurity, or enterprise data roles in the Northern Virginia and D.C. area.

Network Attack Detection & Intrusion Analysis
Deployed Snort IDS on Kali Linux and simulated ICMP, UDP, and TCP SYN flood attacks using Nmap and hping3. Authored custom detection rules achieving 100% alert accuracy and performed Wireshark packet analysis to verify spoofed IP behavior, protocol anomalies, and network-layer responses.

TLS Protocol Implementation & MITM Attack Simulation
Built a TLS client-server system in Python with X.509 certificate verification, SANs, and a root CA, establishing PKI trust chains verified in Firefox. Implemented a multithreaded HTTPS proxy to simulate a Man-in-the-Middle attack, intercepting encrypted traffic by exploiting a compromised CA.

Encryption & Digital Signature Implementation
Implemented a full RSA pipeline covering key generation, encryption, decryption, signing, and verification using 128-bit primes and OpenSSL. Demonstrated the avalanche effect by comparing signatures across minimally modified messages and confirmed that a 2-bit corruption fully invalidates signature verification.
