Protocol researcher, scaling Ethereum L1 and L2

OP Labs 2021–Present

With OP Labs I am working an optimistic rollup: a L2 scaling solution for Ethereum.

Writing specs and code for L2 block-derivation, P2P networking and L1 integration.

Ethereum Foundation 2019–2021

Worked on Ethereum 2.0 as part of the Eth2 Research team.

Helped write specifications, build tooling, deploy testnet infrastructure, optimize implementations, secure mainnet, and prototype new Eth2 features.

The Eth2 project introduces features such as Proof of Stake, LibP2P, and Sharding to Ethereum mainnet.
