PROFILE
Denys Osetrov
Denys Osadchuk developed and enhanced subscription management features for legal entities and products in the Backbase/stream-services repository over a three-month period. He designed and integrated OpenAPI schemas, implemented service methods, and orchestrated subscription provisioning using the Saga Pattern in Java and Spring Boot. His work automated onboarding workflows, improved compliance, and enabled product-level subscription capabilities. Denys also refactored product ingestion logic by extracting reusable utilities, which improved maintainability and reduced future technical debt. He maintained robust unit test coverage with Mockito, addressed test stability after rebases, and ensured release traceability through comprehensive documentation and changelog updates in Markdown.

Jan 1, 2025During 2025-01, delivered end-to-end Product Subscriptions for Products in Backbase/stream-services, enabling product-level subscription capability with an updated OpenAPI schema and integration in BatchProductIngestionSaga. Also fixed test stability for BatchProductIngestionSaga after master rebase by updating mocks and test assertions to reflect recent changes. Overall impact: enables new subscription-driven workflows, improves data consistency across ingestion pipelines, and reduces regression risk in ingestion logic. Technologies/skills demonstrated include API design and schema evolution, saga orchestration, and robust, mock-based test coverage.
