Callum — derived from Latin columba (dove), signifying peace and purity, yet forged in the chaos of offensive security.
0xCa1X —0x(Hex/Web3 roots) +Ca1(Cal, the builder) +X(Xu, the foundation).
I am a researcher by training and a builder by instinct. My work focuses on bridging the theoretical depth of artificial intelligence with the pragmatic reality of cybersecurity and Web3 protocols.
