I build secure systems and break insecure ones. Specializing in cryptographic implementations, vulnerability research, and developing tools that help teams ship more secure software.

ABOUT

I'm a security engineer with a passion for cryptography and building tools that make security accessible to everyone. My work sits at the intersection of offensive and defensive security—I break things to understand how to build them better.

Currently focused on post-quantum cryptography research and developing open-source security tooling. I believe in practical security that works in the real world, not just in theory.

When I'm not hunting bugs or reviewing code, you can find me exploring emerging technologies and constantly expanding my skill set to stay ahead of the latest industry trends.

Cryptography

Implementing and auditing cryptographic systems, from TLS configurations to custom encryption protocols.

Vulnerability Research

Finding and responsibly disclosing security vulnerabilities in software and systems.

Security Tools

Building practical tools that help development teams integrate security into their workflows.

Secure Development

Helping teams adopt secure coding practices and shift security left in the SDLC.

PROJECTS

Open-source tools and research projects focused on making security more accessible and practical.

FEATURED

ChiperCheck

Password strength analyzer that evaluates passwords based on entropy calculation. Provides real-time feedback on password security with detailed entropy metrics and improvement suggestions.
