PROFILE
Roman Udovichenko
Worked on the ydb-platform/ydb repository, delivering four backend features over four months with a focus on data quality, access control, test reliability, and resource management. Leveraged C++ and Python to enhance the YQL DQ provider by improving metadata consistency and constraint handling, reducing data drift across execution modes. Introduced differentiated access control using an isRobot flag, enabling granular feature activation by user type. Improved CI reliability by stabilizing DQ runtime test execution and simplifying test configuration. Developed an automatic time-to-live policy for temporary uploaded files, ensuring efficient storage lifecycle management and preventing resource bloat through automated cleanup mechanisms.

Mar 1, 2026March 2026 (2026-03) — Repository: ydb-platform/ydb. Delivered an automatic time-to-live (TTL) policy for temporary uploaded files, ensuring automatic deletion after a configured duration to improve storage efficiency and guard against resource bloat. Implemented in commit 6b97ff709a7cab3379ef4985f410db6d7cfc892a with the associated PR (#35387) and co-authored by Roman Udovichenko. No major bugs fixed this month. Overall impact: reduced storage costs, cleaner lifecycle management, and faster cleanup of transient data. Technologies/skills demonstrated: backend feature development, storage lifecycle management, TTL-based resource governance, PR-driven delivery, and cross-team collaboration.

Jan 1, 2026January 2026 (2026-01) – Focused on stabilizing DQ runtime test execution in ydb-platform/ydb. Delivered a targeted test configuration enhancement that sets DQ runtime tests to a medium test size for consistent resource utilization, and removed sanitizer-based conditional logic to simplify setup, reduce test flakiness, and improve reliability. These changes were implemented via commit 7fe2997d417af8de01583e7400fae6a80e8c2c7d titled 'Set medium size for DQ runtime tests (#33067)'.

Jul 1, 20252025-07 monthly summary for ydb-platform/ydb: Strengthened data quality reliability and cross-engine metadata consistency in the YQL DQ provider. Delivered targeted constraint handling improvements and expanded validation to ensure parity of DQ results with YQL outputs across DQ and hybrid execution modes. This reduces data drift, improves trust in analytics results, and lowers risk of regressions in production pipelines.
