Worked on the percona/pmm repository to deliver two targeted improvements focused on maintainability and security. Upgraded GolangCI-Lint from v1.55.2 to v1.62.0 within the CI workflow and Makefile, enhancing static analysis coverage and enabling earlier detection of code quality issues. Added the OpenSSF Best Practices badge to the README, signaling a commitment to security best practices and increasing user trust. Utilized Makefile, YAML, and Markdown to align build tools and documentation with current standards. The work emphasized CI/CD process refinement and security-conscious documentation, contributing to higher code quality and more transparent development practices without introducing disruptive changes.
