About
I'm a Computer Science & Engineering student at Northern University Bangladesh with a focused interest in offensive and defensive security. My work centres on penetration testing techniques, SOC workflows, and malware analysis — areas I develop through structured lab practice rather than simulated exercises.
Most of my learning happens hands-on: working through machines and challenges on Hack The Box, completing structured paths on TryHackMe, and building analysis tooling independently. I prefer evidence-based learning over passive study.
I'm currently developing practical skills across web application security, network enumeration, incident handling, and malware analysis. My goal is to build a consistent, documented body of work that reflects genuine technical progress.
