My journey into cybersecurity began with a simple question: "How do systems break, and how can I make them stronger?" Starting with a foundation in Business Administration from CUHK, I discovered that the most powerful tools aren't just technical—they're the ones that understand human behavior and systemic vulnerabilities.

Through automation and workflow optimization, I learned that every system has weaknesses. Whether scripting in Python or building integrations with Google Apps Script, I saw firsthand how small oversights could cascade into major security risks. This drove me to study cybersecurity at TalTech, where I'm mastering the art of breaking systems to build them better.

Today, I specialize in Open Source Intelligence (OSINT) and quantum computing security. My projects explore the cutting edge of digital defense—from building comprehensive OSINT frameworks to simulating quantum-resistant encryption. I believe the future of security lies at the intersection of technology, psychology, and proactive defense.

When I'm not coding or researching, you'll find me CTF competing, contributing to open-source security tools, or writing about the latest threats and defenses. Security isn't just my field—it's my mission to make the digital world safer, one system at a time.
