Worked on the google/flatbuffers repository to address a critical bug affecting iterator correctness when traversing arrays of structures. Focused on enhancing the VectorIterator by fixing its dereference operator, ensuring accurate access to underlying data in complex array layouts. Applied advanced C++ techniques, including template metaprogramming and iterator design, to refactor the IndirectHelper template for robust handling of multiple data types and proper pointer returns. This targeted work improved the reliability and stability of iterator operations, reducing edge-case failures and strengthening the API for downstream consumers who rely on precise data-structure manipulation within FlatBuffers-based applications.
