Worked on the latticexyz/mud repository to deliver a performance optimization for the CLI deployment tooling, focusing on improving deployment speed for existing smart contract worlds. The solution involved enhancing the CLI to read the deploy block number from worlds.json and restricting event fetching to that specific block, which reduced unnecessary data transfer and accelerated deployment times. This approach aligned with the repository’s goal of enabling faster iteration and more reliable deployments. The work was implemented using TypeScript and leveraged skills in CLI development and smart contract deployment, demonstrating a targeted and effective improvement to the full stack deployment workflow.
