About Me
Hello! i’m Er. G. Shankar Sah.
Originally from Nepal, I am a computer engineer with a strong focus on cybersecurity, artificial intelligence/machine learning (AI/ML), and Python development. My interest in digital security began during my undergraduate studies in the early 2000s, and since then, I have dedicated my career to understanding and combating cyber threats.
Over the years, I have gained extensive experience in securing networks, systems, and data across diverse environments. In parallel, I have developed deep expertise as a Python developer, leveraging the language to design and implement robust tools for threat detection, data analysis, and automation.
In addition to my cybersecurity work, I actively explore AI/ML technologies to create intelligent, adaptive security solutions. My combined skills in cybersecurity, Python programming, and AI/ML enable me to build forward-thinking systems that address the evolving landscape of digital threats.
