Message

I'm an independent blockchain security researcher auditing Solidity, Rust, Move, and Cairo protocols across EVM, Solana, Aptos, Sui, and Starknet. I've discovered and reported 50+ vulnerabilities across DeFi, lending, staking, bridges, and DEX protocols through manual review, threat modeling, fuzzing, and attack analysis.

I've also built products including BinDex, a bin-based decentralized exchange, Connectify, a real-time video calling app, and AgentGraph, an autonomous multi-agent framework that resolves GitHub issues through to pull requests. My work spans Node.js, TypeScript, Python, React, Next.js, Docker, Redis, AWS, PostgreSQL, Firebase, and REST APIs.
