Worked on stabilizing RPC interactions for the MystenLabs/walrus-sites repository by addressing dependency management challenges in a Rust environment. Focused on resolving persistent RPC errors, the work involved upgrading the Sui client to version 1.39.0 and updating multiple dependent crates to their latest releases. Changes were primarily made in Cargo.lock and .pre-commit-config.yaml, ensuring that the project leveraged recent library fixes and features. This targeted bug fix reduced the surface area for RPC-related incidents and improved runtime reliability. The approach demonstrated proficiency with Rust, Cargo, and continuous integration workflows, resulting in enhanced production stability for the repository.
