PROFILE

Oleg

Worked on the ydb-platform/ydb repository to enhance backup and restore reliability through targeted test development. Built an end-to-end local backup and restore test suite using Python scripting and system integration techniques, validating the full backup lifecycle including scenarios with pre-existing target tables. Focused on automated testing to improve data integrity checks and streamline CI feedback. Later, implemented C++-based tests for Change Data Capture (CDC) streams rotation on indexed tables, ensuring correct management of backup streams during backup operations. Emphasized backend development, database management, and unit testing to reduce manual intervention and increase the reliability of backup-related workflows.
