Hey ! I'm a junior cybersecurity analyst with experience in network defense and low-level system programming. Background in C/C++ and web development, with hands-on work in security monitoring, threat detection, and automation.


๐ŸŒ€ My Projects

These projects showcase my ability to apply complex technical concepts in real-world scenarios:

Project Title Core Technologies Description
Threat Intelligence Pipeline OpenCTI, Splunk, Zeek, Snort, Caldera Emulated attacks with Caldera and built a fully integrated TI pipeline for automated detection, alerting, and sighting feedback.
Linux HIDS Toolkit Bash, YARA, Sysmon/Logging A custom host-based intrusion detection script for Linux focused on detecting and reporting suspicious activity via log and process analysis.
Limonshello (C Shell) C, Unix System Calls Implementation of a lightweight Unix shell, including process management, command parsing, piping, and redirection.
Custom HTTP Server C++, Networking Low-level implementation of an HTTP server, focusing on networking protocols and handling client requests.
Low-Level Utilities C Reimplementation of core libc functions (e.g., malloc), and network tools (e.g., ping) to deepen understanding of system fundamentals.
