PROFILE
Oleksandra Ishchuk
Worked on Backbase/stream-services to enhance access control workflows and improve backend reliability over a two-month period. Delivered features that integrated external data item IDs into batch updates and introduced reactive processing, reducing latency and improving throughput for permission updates. Managed a major release by updating versioning and documentation, ensuring clear communication of new capabilities. Addressed runtime stability by implementing defensive null checks and preventing exceptions during data group updates, accompanied by targeted unit tests and changelog updates. Utilized Java, the Spring Framework, and version control to deliver maintainable, well-documented improvements that increased data consistency and reduced production risks.
