About
Web3 Security Researcher & Engineer. I got into crypto through security: Smart contract auditing, wallet infrastructure, exchange architecture. ZeroDay Dev started because I couldn't find a good way to practice Web3 security on my phone, something I could do in 5-10 minute increments. So I built it. 3,500+ challenges. 120+ real exploits: Wormhole, Pump.fun, Balancer, Yearn. Mobile-first, offline. $4.99 once, no subscription. Also built ParallelPool, a shared liquidity primitive for Monad addressing flash loan vulnerabilities unique to parallel EVMs. Bug hunting on Code4rena, Cantina, Sherlock, Immunefi.
