Worked on the cosmos-sdk repository to optimize Cosmovisor’s auto-download process by removing a redundant validation step, which previously caused duplicate binary downloads and unnecessary operational overhead. This change improved upgrade efficiency and reliability for Cosmos-based networks. In parallel, updated the zeta-chain/docs repository to clarify TSS direct deposit support, specifying Ethereum-only compatibility, and added detailed sections on the Call functionality and E2E development environment. These documentation enhancements provided clearer guidance for developers integrating cross-chain features. The work combined Go for backend improvements and Markdown for documentation, demonstrating skills in bug fixing, DevOps, and tooling within a collaborative open-source environment.
