Stockholm, Sweden, mail me

Welcome to my GitHub profile! I’m a recent MSc graduate in Networked System Security from KTH Royal Institute of Technology, with experience in wireless security, Linux kernel development, and privacy-enhancing network protocols. I enjoy working at the intersection of systems, security, and real-world networking.

About me

  • Recent Role: Completed a visiting scholar researcher at KU Leuven (DistriNet), focusing on enterprise Wi-Fi security and protocol misconfigurations.
  • Upcoming Paper: Co-authored a paper on certificate misconfigurations in WPA2/3 enterprise networks, accepted to CSNet 2025 (to appear soon).
  • MSc Thesis: Developed and evaluated a MAC address re-randomization protocol inside the Linux mac80211 stack to defend against WiFi tracking.
  • Skill Set: Proficient in C, C++, and Python, with hands-on experience in network security protocols, Linux kernel development, and embedded systems.
  • Interests: Wireless security, privacy protocols, and networked system optimization.

AP-Initiated Dynamic MAC Re-Randomization

  • Developed a Dynamic MAC re-randomization protocol in the Linux kernel to address WiFi tracking risks.
  • Integrated wmediumd and Mininet-WiFi to simulate real-world scenarios, achieving high privacy without compromising network performance.
  • Conducted tests to analyze network impact, visualizing MAC transitions and linking accuracy.
  • Support Repository: Check out for additional testing resources.

Other Projects

  • Building Networked Systems Security: Designed a secure VPN-based network for remote data exchange, utilizing OpenVPN, OpenSSL, Docker, and RADIUS for secure access control.
  • Facial Recognition Attendance System: Built an automated attendance system using OpenCV, face-recognition.
