Biography

Biography

Hey! J here! 👋🏾

I’m a security researcher with 5 years of experience in auditing and vulnerability research across EVM, SVM, and Move ecosystems.

I previously spent 3 years as a Solidity developer before transitioning fully into security, where I led the Security Department at Sixfoot as a Security Engineer.

I am also a founding contributor to the Sui Prover at Asymptotic, where I worked on formal verification tooling for Sui Move.

Today, I specialize in Move-based ecosystems, formal verification, and smart contract security. I’ve been actively triaging reports on Cantina for over a year, reviewing and validating real-world vulnerability submissions at scale.

Across my career, I’ve worked with protocols such as Aave, LayerZero, Coinbase, Flying Tulip, and Navi, among others. My audit experience spans cross-chain bridges, CLMMs, lending markets, staking systems, perpetuals, and DeFi infrastructure primitives, to name a few.
