I was a core member of PolyNetwork and EthStorage, am also among the top 50 contributors of go-ethereum and many other blockchains. Recently my focus has been switched to zkp and I contributed several PRs to zk projects like aleo. I'm also leading the izar bridge which is dedicated to bridging assets from other blockchains to aleo in a decentralized and private way, here for a glance of this project: https://github.com/izar-bridge/eth-contracts .
