Hackathon CND - Machine Learning for Cybersecurity	Hackathon	Commissariat au numérique de défense (CND), French Armies ministry	https://www.defense.gouv.fr/cnd	Fort du Mont-Valérien, Suresnes, France	2025-11	2025-11	3 days	Developed a Python ML pipeline during the CND hackathon to classify system logs for bug and attack detection. Implemented feature extraction and preprocessing, trained and evaluated models (tree-based and lightweight neural), tuned thresholds to favor recall, and delivered a realtime prototype with visualization and reproducible code in collaboration with CND engineers. Implemented a Streamlit application to test the classifier interactively and used an LLM to generate contextual help explaining the likely origin and indicators of detected bugs or attacks for end users.
