PROFILE
Antonios-konstantinos Pappas
Worked on the os-autoinst/os-autoinst-distri-opensuse repository, delivering reliability and automation improvements for enterprise Linux testing and deployment workflows. Addressed system administration challenges by refactoring installation and repository management logic, enhancing SELinux integration, and stabilizing high availability test scenarios. Applied Perl and shell scripting to automate package management, synchronize filesystems, and manage SAP and HANA deployments, reducing manual intervention and deployment failures. Improved CI stability by resolving race conditions, deadlocks, and asset handling issues, while extending test automation to support transactional and immutable system platforms. Demonstrated depth in debugging, DevOps, and test automation, consistently linking changes to traceable commits.

May 1, 2026May 2026: Delivered High Availability (HA) Testing Framework Enhancements and Immutable System Platform Support for os-autoinst/os-autoinst-distri-opensuse. Implemented transactional-system aware package installation via package_utils::install_package, switched ClusterTools2 installability checks to zypper se for universal applicability, and removed an unnecessary zypper up to ensure systems are fully patched before test execution. Extended ha_2nodes scenarios to support transactional environments and immutable infrastructures on PPC and s390x, enabling HA testing across additional architectures (related to TEAM-11014).

Apr 1, 2026April 2026: Delivered a reliability-focused refactor for HANA repository management in os-autoinst/os-autoinst-distri-opensuse. Replaced direct edits to repos.d with addrepo calls via PC library functions to prevent zypper lock issues and error 7, improving the reliability of adding repositories for HANA instances. This change reduces deployment fragility, lowers manual troubleshooting, and supports smoother onboarding of HANA deployments. Demonstrated strong skills in system packaging automation, refactoring for stability, and cross-team collaboration, aligning with the related ticket TEAM-10382.
