Matheus Stolf developed content-control filtering enhancements for the ntop/nDPI repository, focusing on safer internet experiences for children. He implemented new filtering categories—such as search engines, children, violence, drugs, and weapons—by extending the protocol detection pipeline in C. Matheus also introduced a dedicated protocol identifier for YouTube Kids, enabling more granular monitoring and enforcement of content policies. His work integrated these features into the existing network programming framework, supporting improved observability and policy management. Over the course of one month, Matheus demonstrated depth in protocol development and content filtering, addressing the need for precise traffic classification without fixing existing bugs.
