I’ve helped secure and scale 12+ DeFi products, deploying production-grade protocols across EVM-compatible chains and Solana. My work spans cross-chain lending systems, leverage vaults, and decentralized on/off-ramp infrastructure — with a focus on liquidity aggregation, cross-border payments, asset management, and real-world asset tokenization. What I Do: Design and deploy secure smart contracts and complex DeFi systems Architect and scale cross-chain infrastructure, integrated with over 10 protocols including Kyber, GMX, Near-Protocol, EigenLayer, and more. Conduct in-depth security research and audits on platforms like Sherlock, Code4rena, and CodeHawks, Cantina.
