Technical Profile

Computer Engineering student specializing in system-level security, endpoint defense, and security data analytics. I focus on engineering lightweight security agents, automating reconnaissance workflows, and parsing low-level system telemetry. Deeply passionate about Linux internals and building memory-safe defense utilities from scratch.


Core Technology Stack

Operating Systems & Shell Infrastructure

Arch Linux Linux Bash

Languages & Security Tooling

Python C# C++

Data Science & Telemetry Analytics

Pandas NumPy Matplotlib


Featured Projects

A lightweight, continuous File Integrity Monitoring (FIM) agent engineered for Linux environments.

  • Memory Optimization: Implemented 4KB data chunking to cryptographically hash (SHA-256) multi-gigabyte files safely without triggering Out-Of-Memory (OOM) failures.
  • Noise Reduction: Integrated intelligent runtime whitelisting to eliminate alert fatigue caused by dynamic directories (.venv, __pycache__).
  • Deployment: Bundled with an automated one-liner Bash installation script for native system deployment.

A Python-based system auditing and reconnaissance script designed for security hardiness checks.

  • Telemetry Automation: Automates the gathering of critical system metrics, hardware architecture, and environment baselines.
  • Network & Privilege Auditing: Scans active network interfaces and conducts user privilege verification to detect potential security misconfigurations.
  • Structured Output: Generates clean, human-readable security and operational baselines directly within the Linux terminal.

A Python data analytics workflow simulating SIEM ingestion pipelines.

  • Data Processing: Uses Pandas for data ingestion, missing value imputation, and tactical risk score modeling.
  • Visual Analytics: Leverages Matplotlib and Seaborn to visualize attack distribution vectors (DDoS, SQLi, Phishing).
