Worked on the Altinity/ClickHouse repository to improve documentation hygiene and streamline CI/CD processes. Focused on removing outdated binary installation instructions for unsupported platforms, ensuring the documentation accurately reflects current platform support and reducing confusion for users. Utilized Markdown for documentation updates and Git for version control, coordinating changes through a targeted commit. Also cleaned up unused CI workflows and third-party buckets, which simplified maintenance and reduced operational risk. The work demonstrated skills in documentation management and CI/CD workflow optimization, contributing to lower support overhead and more maintainable project infrastructure. No new features were added, but one bug was resolved.
