Worked on the EPPlus repository to enhance Ahead-of-Time (AOT) compilation support for Excel VBA collections, focusing on improving reliability and cross-platform deployment. Refactored the collection access layer by removing reflection-based property access and introducing the IExcelVBACollectionElement interface, updating ExcelVBACollectionBase to use direct property access instead. This approach reduced the risk of NullReferenceExceptions in AOT-compiled VBA macro scenarios and aligned with broader deployment goals. The work leveraged C# and skills in AOT compilation, interface design, and reflection, resulting in a targeted feature that improved stability and performance for VBA macro workflows without addressing major bugs during the period.
