PROFILE
Oleg Popko
Over ten months, contributed to arenadata/SSM by building and expanding robust automated testing and backend features, focusing on API integration, UI workflow validation, and data replication reliability. Developed comprehensive test suites for Rules, Actions, Audit, and Cluster modules, leveraging Java, Selenium, and Groovy to ensure accurate sorting, filtering, and pagination across APIs and user interfaces. Enhanced CI/CD pipelines and modularized test environments using Docker and Maven, improving feedback cycles and deployment safety. Addressed system stability through targeted bug fixes, refactoring, and test infrastructure improvements, while implementing database management and Hive Metastore replication to support scalable, reliable data workflows.

7 Commits • 1 Features
Mar 1, 2026March 2026 — Arenadata/SSM: Delivered HMS replication enhancements with comprehensive testing (replication events, HMS stats replication) and SSM metastore replication improvements including improved logging and database management. Also stabilized the HMS Sync Rule test suite by fixing correctness, refactoring pagination tests, resolving sequence issues in action logs for DB operations, and adding a retry mechanism for flaky tests. Business value: more reliable data replication, faster validation cycles, reduced toil in QA, and clearer observability. Technologies demonstrated: Java, AQA/test automation, test fixtures, robust logging, retry patterns, and database operation sequencing.
