Biography

I've been involved in the security ecosystem since early 2020 and since then my passion for finding interesting bugs has only grown. Over the years, I have gained exposure to many facets of DeFi and other types of smart contract infrastructure.

The list is growing, but I have expertise in the following areas of smart contract security:

  • Cross-chain liquidity and messaging bridges
  • Institutional credit markets
  • Collaterized/undercollaterized borrowing and lending utilizing fixed or variable rates
  • AMMs
  • Liquid staking derivatives (LSDs)
  • Collateralized crypto assets
  • Portfolio management applications
  • NFT marketplaces and tokenization
  • Stablecoins
  • Index tokens
