About Me

Shikarpur, Sindh, Pakistan

I am an IT professional with a BSIT from The Shaikh Ayaz University and a deep passion for building systems that are both secure and intelligent. My technical journey spans Linux system administration, network hardening, and applied machine learning — fields I treat as deeply interconnected.

On the security side, I specialize in Kali Linux environments, Windows Server configuration, and the full suite of network protocols. I approach every system with a security-first mindset — asking not just "does it work?" but "is it hardened against real threats?"

In AI/ML, I have built production-grade CNN pipelines for medical imaging diagnosis and implemented autonomous robotics navigation with A* pathfinding in ROS Noetic. I believe the convergence of cybersecurity and AI represents one of the most important frontiers in modern technology.

Beyond corporate IT, I am actively exploring opportunities as a Junior Science Teacher — motivated by a genuine desire to equip the next generation with technical literacy and critical thinking skills.
