# About Me

I specialize in bridging the gap between high-performance software engineering and advanced cybersecurity principles.

With over a decade of experience in the tech sector, I have engineered zero-trust cloud architectures, audited complex smart contracts, and designed scalable microservices in Rust, Go, and TypeScript.

My philosophy revolves around minimalism, robust threat modeling, and writing clean, testable code that withstands adversarial conditions. When not optimizing encryption protocols, I contribute to open-source pentesting toolsets.
