Security researcher specializing in web3 and blockchain security. I find vulnerabilities in smart contracts, audit decentralized infrastructure, and build tools that help secure the next generation of financial systems.

}I focus on high-impact security work at the intersection of cryptography, distributed systems, and adversarial thinking:
- Smart contract auditing — identifying logic flaws, access control issues, and economic attack vectors in Solidity/Vyper codebases
- Web3 infrastructure security — auditing crypto wallets, RPC nodes, bridges, and protocol implementations
- Vulnerability research — discovering zero-days and coordinating responsible disclosure with project teams
- Security tooling — building analyzers, fuzzers, and automation frameworks for blockchain security testing
- Smart contract vulnerability patterns across DeFi protocols
- Attack surface analysis of blockchain nodes and consensus mechanisms
- Security-critical components in cross-chain bridges and interoperability layers
Languages: Solidity, Vyper, Python, JavaScript/TypeScript, Rust
Tools: Foundry, Hardhat, Slither, Echidna, Manticore, Mythril
Domains: EVM internals, DeFi protocols, cryptographic primitives, threat modeling
Security isn't about checkboxes. It's about understanding how systems break under adversarial conditions—and building defenses that hold up when money is on the line. I combine deep technical knowledge with real-world attack modeling to identify risks others miss.
Open to:
- Security audits and consulting for web3 projects
- Research partnerships on novel attack vectors
- Contributing to open-source security tooling
- Speaking engagements on blockchain security
