Biography
Prior to shifting to web3 security, I was a software engineer for ~10 years and worked with languages like Golang, Elixir, Ruby, JS, to name a few. My interest in distributed systems and cryptocurrency led me to study smart contract development and then web3 security.
Since working as a web3 security researcher, I have helped secure ~$3 Billion worth of TVL across all the chains and protocols I've audited.
As a security researcher, I am particularly interested in the following:
- L2s (have audited Optimism with Trust Security, Blast on Cantina, and zkSync on Code4rena)
- Cross-chain Messaging (LayerZero, Wormhole, Chainlink's CCIP)
- DeFi (stablecoins, integrations with other DeFi protocols, token-wrapping, yields, and vaults)
- Liquid Staking Tokens (Eigenlayer, Lido)
I've done private audits as part of a team in the following protocols:
- Optimism
- Reserve Protocol
- Timeswap
I am currently affiliated with the following exclusive auditing firms:
- Trust Security - https://trust-security.xyz/
- Spearbit - https://spearbit.com/

| Reserve Audits and Retainer - Trust Security | As part of Trust Security, I have done multiple audits on Reserve Protocol along with cccz and HollaDiewaldfie. Our initial audit was a 6-week audit of the whole codebase which eventually led to a retainer that is still currently active. |
| Timeswap V2 Audit - Trust Security | This audit was done as part of Trust Security and I teamed up with @jeiwan. Timeswap is a fixed-rate lending protocol with a unique 3-variable constant product AMM. Its code is largely influenced by UniswapV3 and makes heavy use of storage packing and binary fixed-point arithmetic. |
| Optimism Audit - Bedrock Upgrade - Trust Security | I teamed up with Trust on this under Trust Security. The audit scope was on a new Pause functionality that was added to their L1 and L2 contracts. We were able to identify a High finding in one of the inherited contracts that was missed in previous audits. |
