I also developed bulk payment services for enterprise clients and designed reconciliation workflows for Treasury reporting to the Central Bank of the UAE.
As a Blockchain & Smart Contract Security Researcher, I review DeFi and blockchain protocols and build working PoCs and regression tests. My findings include high-severity authorization and liquidation issues, plus XRPL transfer-fee and asset-authorization bugs.
