Key Projects

  • Ransomware-Detector (Python | Security)
    Python security tool for real-time ransomware detection, using filesystem monitoring, entropy analysis, fuzzy-hashing and honeypots to flag suspicious encryption activity.

  • Atom-Molecule-System (C | Systems, Network)
    Concurrent C server simulating an atom-molecule model, featuring TCP, UDP and Unix domain sockets, shared-memory persistence and a command-driven protocol.

  • Reversi-Game (Java | OOP)
    Extended Java Othello game with custom disc mechanics, AI opponents and a Swing-based GUI, developed as part of an Object-Oriented Programming project.

  • Coup-Game (C++ | OOP, SFML)
    C++ implementation of the popular Coup card game, built with SFML for GUI and designed with OOP patterns (inheritance & polymorphism).

  • Phishing Email (Python | Security)
    A lab-controlled phishing simulator with social engineering emails, malicious attachments, and DNS tunneling for safe demonstration of cyber threats.

  • Network-Traffic-Analysis (Python | Network)
