During March 2025, Greenik71 focused on enhancing reliability and correctness within the elsa-core repository by addressing two critical bugs in backend workflow operations. Working primarily with C# and leveraging skills in API and database development, Greenik71 improved the Store.DeleteAsync method to ensure filters are applied before parameter evaluation, enabling more accurate and predictable delete queries. Additionally, they refined the Variable class constructor to properly assign custom identifiers, preserving intended object identity. These targeted changes strengthened data integrity and reduced the risk of silent failures, reflecting a thoughtful approach to core software maintenance and robust backend engineering within the project.
