Experience
- BPCE-ITData scientistTECHApril 2024 - October 2024 (6 months)Paris, FranceDuring my internship at BPCE Infogérance & Technologies, I analyzed 500,000 internal logs using the DistilRoberta LLM model to identify and mitigate 90% of potential anomalies. I deployed an interactive dashboard to monitor Splunk index volumes, reducing response times by 40%. Additionally, I examined over 1 million authentication logs to detect suspicious activity patterns, improving detection accuracy by 30%. I also developed Splunk dashboards to monitor VM activities, enabling the identification of inactive machines. My work significantly enhanced the company’s operational efficiency and security monitoring capabilities.
- Etis labResearch assistantEDUCATION AND E-LEARNINGOctober 2023 - March 2024 (6 months)Cergy-Pontoise, FranceAs a Research Assistant at ETIS Lab, I synthesized four sequential datasets (600 records each) to optimize the performance of RNNs for behavioral pattern analysis. I created a flexible RNN model with adjustable components (LSTM, GRU, Elman) using a modular architecture, achieving 90% accuracy in mimicking human decision-making. I also conducted a comparative analysis of various model configurations, identifying key settings for optimal performance. My contributions advanced the lab’s research in neural networks and decision-making systems.
- Ecole PolytechniqueData scientistEDUCATION AND E-LEARNINGJanuary 2023 - May 2023 (5 months)At EMP, I enhanced the CIC-IDS-2017 dataset using SMOTE to address class imbalance, resulting in a 10% increase in detection accuracy. I developed an intrusion detection system (IDS) based on XGBoost, achieving 92% accuracy and outperforming benchmarks such as Random Forest and SVM. I also provided insights into explainable AI using SHAP and LIME, improving the interpretability of the model. My work contributed to more robust and transparent cybersecurity solutions.
