PROFILE
Dries Samyn
Dries Samyn worked on simplifying the ledger persistence layer in the corda-runtime-os repository by removing Hibernate and JPA dependencies and refactoring the UtxoPersistenceServiceImpl to use direct JDBC connections with native SQL. This backend development effort focused on reducing ORM complexity, streamlining database management, and lowering future maintenance costs. By leveraging Java, Kotlin, and SQL, Dries improved the clarity and maintainability of the persistence path, laying the groundwork for faster performance tuning. The work demonstrated a deep understanding of dependency management and persistence frameworks, resulting in a more transparent and efficient architecture for future development and iteration within the project.
