Experience

Senior Smart Contract Security Researcher
Trugard Labs

Core developer on a real-time blockchain security monitoring system, building and maintaining production-grade security detectors across live EVM chains. Designed and implemented rule-based static & dynamic detectors like: Library tampering, Malicious mint/burn paths, transfer & approval blocking mechanisms, suspicious external calls & balance updates, etc. Improved detection coverage & reduced false positives using mix of rule-based & ML-driven approaches. Engineered opcode-, CFG-, and storage-level features for ML-based vulnerability detection models, and validated predictions against real-world exploits and false positives. Modeled real-world exploit flows like access control bypass, state manipulation attacks, input validation, etc. Built and extended code analysis pipelines (AST, CFG, bytecode parsing) and performed fuzzing and mainnet-fork simulations. Caught in production: traced OpenZeppelin library tampering to a $1M live scam on Base Network.
