01. Who I Am
About Me
Background
Born on January 6, 2002, in Magura, Khulna Division, Bangladesh. Raised in a family that values discipline, education, and integrity, I developed an early fascination with technology and problem-solving. From district-level science fairs to competitive programming, I built the analytical foundation that now drives my cybersecurity research.
Career Objective
Aspiring to become a cybersecurity engineer and digital forensics specialist. I am driven by the challenge of building resilient systems, uncovering vulnerabilities in web applications, and developing AI-powered tools that create meaningful social impact — particularly in online safety and gender-based violence prevention.
