Electrical & Computer Engineering student at the University of Peloponnese, specializing in Computer Science. Focused on defensive security (blue team), privacy-oriented tooling and digital forensics.

• dnser — Terminal-first DNS switcher for Linux. Detects your DNS backend (NetworkManager/systemd-resolved), applies changes through its native mechanism, snapshots & reverts cleanly. DoT, fallback DNS, latency benchmarking, atomic writes. Privacy-oriented, one job done right.

• sshd-lint — Static analyzer for sshd_config. Encodes OpenSSH hardening best practices into repeatable, automated checks so misconfigurations get caught before they ship.

• probolos (alpha) — USB port monitoring and control tool aimed at physical-access and data-exfiltration risks. Successor to an earlier prototype (cerberus); still early days.

• audiotap — Audio capture for Linux. Reads raw PCM from the PipeWire/PulseAudio monitor source, splits tracks live using MPRIS metadata over D-Bus, and encodes each one through ffmpeg with tags preserved. Single-file Python, stdlib only.
