đź”’ Senior Blockchain Engineer with expertise in blockchain security, smart contract development, and on-chain analysis. With 50+ audits to my name, I have worked on a wide range of protocols, from simple tokens to much more complex systems like cross-chain bridges and multisig wallets.
In addition to security audits and development, I specialize in on-chain analysis:
- Tracking Stolen Funds: Following fund flows across multiple blockchains.
- Hack Investigations: Post-incident analysis to identify vulnerabilities.
- Conclusion Reports: Providing analysis and recommendations to aid in fund recovery and legal cases.
I help teams secure their blockchain solutions, recover lost assets, and ensure their protocols meet the highest standards of reliability and performance.
