"An ethical hacking project focused on exploring vulnerabilities in NFC-enabled ATM cards. It analyzes security flaws and attack vectors, demonstrating potential exploits in NFC-based financial systems for educational purposes. This project is part of my cybersecurity studies to enhance understanding of NFC security risks."

VictimLocator-360 is an advanced, AI-integrated hybrid system that combines hardware and software to enhance search and rescue operations in collapsed structures.

NEC uPD7725 and uPD96050 DSP emulator in Python, cycle accurate. Held to NEC's data book for every flag each ALU operation touches and to a per-encoding corpus for the whole processor state: 1,002,240 instructions compared, zero disagreements. 100% branch coverage, no firmware ever
