Worked on enhancing vector indexing capabilities in the ArcadeData/arcadedb repository by adding support for List<Float> data structures, expanding beyond the existing float array indexing. This feature enabled more flexible and ML-ready data handling for vector-based analytics, aligning with evolving business requirements for broader data modeling. The implementation maintained backward compatibility while introducing new logic to efficiently process both float arrays and lists, addressing performance and flexibility needs. Leveraged skills in Java, algorithm design, and data structures to deliver a focused, well-scoped change. The work demonstrated disciplined change management through targeted commits and careful attention to compatibility and extensibility.
