Worked on the stellar/quickstart repository to deliver a Docker-based Rust toolchain setup for the Stellar XDR CLI, focusing on improving build reproducibility and developer workflows. Updated the Dockerfile to ensure the Rust toolchain is installed only if not already present, enabling seamless use of cargo install and supporting the building of the stellar-xdr binary with CLI features inside the container. This approach standardized the Rust environment across local and CI setups, streamlining both development and automation processes. The work leveraged skills in build automation, DevOps, and Rust, with Dockerfile and Rust as the primary languages and technologies used.
