about

I'm a 16-year-old independent security researcher focused on offensive security R&D, low-level systems, and applied cryptography.

My work explores obfuscation & exfiltration techniques, command & control architecture design, cross-platform tooling, protocol engineering, and cryptographic primitives. I enjoy rewriting systems across languages to understand them deeply.

selected work

Obfuscation & Packer Research, Reverse Engineering
Experimental tooling exploring obfuscation strategies, loader/packer design, and reverse engineering shitty malware samples.
Cross-Platform C2 Architecture (R&D)
Multiple research projects focused on modular command routing, transport abstraction layers, evasion & exploitation techniques and scalable backend design.
Cryptographic Library Development
Work on cryptographic primitives and modern curve integrations, with an emphasis on performance and mathematically secure implementation.
Systems Rewrites & Language Migration
Ongoing experimentation rewriting tooling in C++, Go, Nim, and Elixir to improve performance and architectural multithreaded balance & asynchronous requests.
