Tamir worked on the stellar/quickstart repository, focusing on build automation and CI/CD pipeline improvements over a three-month period. He upgraded the build configurations to consistently track the latest stable Horizon releases, updating workflow files, Makefile, and Dockerfile to align horizon_ref and friendbot_ref versions. By introducing explicit version pinning and upgrading the build environment to Go 1.23, Tamir reduced build drift and improved reproducibility across development and CI environments. His work leveraged Dockerfile, YAML, and Makefile expertise to streamline release management, enhance test reliability, and ensure compatibility between local development and automated CI pipelines, supporting faster and more stable releases.
