Worked on SciMLBase.jl to deliver a compatibility layer for SDEFunction, enabling seamless integration with SciMLOperators v1 and future versions. Developed new callable methods in Julia, incorporating conditional dispatch logic to detect AbstractSciMLOperator and route calls to the appropriate implementation. This approach ensured backward compatibility while supporting migration to updated operator APIs, reducing potential runtime errors and maintenance overhead. The work enhanced interoperability and flexibility for developers interacting with SciMLOperators across versions. By focusing on robust software engineering practices, the changes improved the developer experience and streamlined downstream integration, addressing a critical gap in the SciMLBase.jl ecosystem.
