Hi Optimism fans, I'm Joohhnnn, a big fan of Optimism just like you. I've been a developer for three years and have submitted some PRs to Geth, the Ethereum ecosystem, and op-node. I'm also part of EPF4 (Eth-Protocol-Fellows), and am working on the project "Optimism-Sequencer-Support-for-ERC-4337-Bundlers". Plus, I've written many articles for developers to explain how Optimism works. Additionally, I've created a tool to adapt Optimism's devnet and bundler, enhancing the workflow for developers.
