PROFILE
Shams Asari
Worked on the corda/corda repository over four months, focusing on backend development and test reliability using Kotlin and AssertJ. Improved the UniquenessProvider by adding idempotency checks and strict time-window validation, reducing duplicate processing and invalid inputs. Enhanced test infrastructure for the Notary service by refactoring and consolidating test bases, which streamlined maintenance and enabled future feature compatibility. Migrated deprecated Kotlin assertions to AssertJ, increasing test reliability across JVM configurations and reducing flakiness in CI. Expanded and reorganized test coverage for notarisation processes, clarifying executor behavior and ensuring correctness across different execution environments through targeted test-driven development and refactoring.

Jun 1, 2025June 2025 monthly summary focusing on CordA's stability and maintainability improvements. Delivered robustness enhancements to the UniquenessProvider by introducing idempotency checks and strict time-window validation, significantly reducing the risk of duplicate processing and invalid inputs. Implemented targeted logging level adjustments for Hibernate to improve runtime debugging and issue diagnosis. These efforts were supported by expanded test coverage for UniquenessProviderTests to validate new edge cases, aligning with ENT-13465. The work was tracked with commit 23c7ac7765af6c5e3c87e3e6ebde8093f3cd95b9.
