Fabio worked on the ntop/nDPI repository, focusing on stabilizing and optimizing the ndpiReader tool for duration-based live network captures. He addressed memory management and lifecycle issues in statistics handling, refactoring the initialization, reset, and freeing sequences to enable safer reuse of data structures and reduce the risk of crashes. Fabio also implemented a memory-optimized refactor for ndpi_flow_info, dynamically allocating src_name and dst_name based on IP version to lower RAM usage. Using C programming, multithreading, and performance optimization techniques, his work improved reliability and scalability for high-flow deep packet inspection, demonstrating depth in system-level engineering and debugging.

Jul 1, 2025July 2025 performance summary for ntop/nDPI: Implemented a memory-optimized refactor by making ndpi_flow_info's src_name and dst_name dynamically allocated based on IP version. This eliminates pre-allocated IPv6 buffers when not needed, reducing RAM usage significantly. The change includes null-pointer safety checks and proper deallocation when flow info is freed, improving safety and reliability under high-load conditions. Commit reference: 4eff2cdb9991eed51e7e00e4dcc2f5fa1955cf17 ("Refactor: make src_name/dst_name dynamically allocated to reduce RAM usage (#2908)").
