Cybersecurity researcher & malware analyst forging defenses in the dark. Blockchain architect. Quantum cryptographer. CTF warrior.

About

Every project, paper, CTF, and contribution — archived here. My work spans offensive & defensive research, privacy-first protocols, and secure-by-design systems. Like the katana forged through fire and folding, every line of code is deliberate.

Projects

Security Compliance Platform (Enterprise)
On-premises HIPAA compliance platform with continuous monitoring, EDR, SIEM integration, and quantum-enhanced encryption.
  • File scanning (VirusTotal-like), sandbox execution, YARA-based static analysis, ClamAV, AI-based detection
  • Zero Trust architecture, UEBA, automated compliance reporting, audit-readiness pipelines
Blockchain-Based Secure Drone Logistics Network
Private blockchain storing drone registration & telemetry with P2P network and real-time tracking map.
  • On-chain drone events, tracking map integration, decrypt.py for live location fetching
  • DB: drones_blockchain.db
Tor-Only Anonymous Chat Protocol
Design + prototype for anonymous, onion-routed chat with metadata minimization and perfect forward secrecy.
  • Protocol-level anonymity assumptions, PFS, end-to-end encryption via Tor transport
D-Anon — De-anonymization Research Tool
Traffic analysis research tool for tracing correlation techniques and traffic fingerprinting (research-only, ethics-first).
  • Traffic fingerprinting, ethical disclosure workflows, correlation analysis engine
Ransomware Research & PoC (Academic)
Polymorphic & metamorphic payload research for evasion analysis and defensive measures — academic and ethical use only.
  • Mutation-based ransomware for evasion studies; CTF-style negotiation simulator using smart contracts
PiGuard — Network Access Control
Raspberry Pi-based access control logging and unknown device detection system.
  • Sector 2: Python backend with SQLite logs, periodic detection intervals, real-time alerts
Real-time Host Scanner
Python backend scanning open ports, monitoring services, sandbox-executing incoming files — logged to SQLite every 10s.
  • Planned: Raylib GUI in C displaying backend terminal output in real-time
