About Me

My Journey

I'm a cybersecurity enthusiast and developer passionate about building secure systems and solving complex security challenges. My journey in cybersecurity began with a curiosity about how systems work under the hood and evolved into a mission to make the digital world safer.

From participating in CTF competitions to building security tools, I constantly push myself to learn and grow. I believe in learning by doing, which is why I actively contribute to open-source projects and share my knowledge through writeups and tutorials.

My approach combines theoretical knowledge with practical implementation, allowing me to not just understand vulnerabilities but also build solutions that address them.

Currently Focused On

  • Building secure infrastructure and DNS solutions
  • Developing AI-powered security tools and retrieval systems
  • Contributing to open-source cybersecurity projects
  • Exploring modern web security and penetration testing

What Drives Me

I'm driven by the challenge of solving complex security problems and the satisfaction of building tools that make a real-world impact. Whether it's discovering a vulnerability, automating a security process, or teaching others about cybersecurity, I'm always looking for ways to contribute to the community.
