PROFILE
Anna Mikhlin
Worked on the scylladb/scylladb repository, delivering features and reliability improvements across CI/CD automation, version management, and backend infrastructure. Developed GitHub Actions workflows in Python and YAML to automate Jenkins CI triggers via issue comments, reducing manual intervention and accelerating feedback cycles. Enhanced CI stability by refining trigger logic, preventing false positives, and implementing bot exclusion to avoid redundant builds. Upgraded ScyllaDB development versions to maintain release hygiene and support new features. Improved S3 client resilience for CI tests by adding retry and timeout handling using AWS SDKs. Demonstrated strong skills in DevOps, backend development, and version control practices.

Jun 1, 2026June 2026 monthly summary for scylladb/scylladb focused on CI reliability improvements through S3 client resilience: - Implemented explicit retry and timeout handling for the S3 release-listing path to mitigate transient network issues during CI tests. - Aligned S3 client settings with the existing retry resilience pattern used by the download path (timeouts and adaptive retries). - Linked to RELENG-632 and closed scylladb/scylladb#30535 for traceability and closure of related defects.

Feb 1, 2026February 2026 (scylladb/scylladb): Delivered a targeted CI reliability improvement by tightening the trigger logic for CI runs. Implemented validation/cleaning of comment text to ensure trigger-ci is only recognized in unquoted text, preventing false CI triggers when the command appears in quoted comments. This change reduces unnecessary CI executions, improves pipeline stability, and accelerates feedback to developers. The work aligns with reliability and cost-efficiency goals for the CI/CD process and directly supports faster release cycles.

Aug 1, 2025August 2025: Delivered CI Trigger Automation via Issue Comment for the scylladb/scylladb repository, establishing an automated bridge between GitHub issues and the Jenkins-based CI pipeline. The new GitHub Actions workflow listens for issue comments containing '@scylladbbot trigger-ci' and triggers the Scylla-CI-Route Jenkins job, sending PR information to initiate CI runs automatically. This reduces manual CI triggering steps, accelerates feedback, and improves CI reliability across changes.
