Developed and delivered a Helix-based Secondary Vertex Factory for the EICrecon repository, expanding its reconstruction capabilities by introducing a new SecondaryVerticesHelix factory within the reco plugin. This feature enables more precise secondary vertex reconstruction by leveraging advanced algorithm development and data analysis techniques in C++. The implementation stores vertex data using the PODIO framework (edm4eic:Vertex) and is supported by a comprehensive test suite and updated documentation to ensure reliability and ease of integration. The work focused on end-to-end feature delivery and validation, with close collaboration among contributors, and did not involve major bug fixes during the development period.
