About

I am a blockchain investigations professional with a law enforcement background, specializing in crypto-related financial crime, asset tracing, and the operational support of criminal investigations involving digital assets. In my current role, I support investigations into crypto-enabled fraud and related financial crime by tracing blockchain transactions, identifying investigative leads, supporting seizure and asset recovery measures, and collaborating with internal stakeholders as well as international virtual asset service providers under AML-related requirements. My work combines analytical rigor, investigative thinking, and practical case support. I am particularly interested in roles at the intersection of blockchain intelligence, financial crime investigations, public-private cooperation, and cross-border asset tracing. Certified in both Chainalysis and TRM Labs tools, I am especially interested in connecting with teams working on crypto investigations, illicit finance, scam disruption, sanctions, compliance, and intelligence.
