- Designed and implemented an unsupervised anomaly detection pipeline to identify suspicious banking transactions using the Isolation Forest algorithm. - Worked on real-time fraud detection for internal banking operations with a focus on reducing false positives and improving model robustness. - Applied feature engineering, PCA, and hyperparameter optimization using Optuna, boosting model precision and recall on imbalanced datasets. - Conducted robustness testing by injecting Gaussian noise and evaluated performance using metrics such as AUC-ROC, F1-score, and stability index. - Collaborated closely with data scientists and business analysts in an Agile/Scrum environment, using JIRA for sprint planning and task tracking. - Deployed the model in a secure Data Lab environment, integrating it with daily scoring systems for transaction monitoring.

During my internship at AREF de Guelmim-Oued Noun, I conducted an in-depth analysis of payment delays using advanced web scraping techniques and data visualization with Power BI. I extracted, processed, and visualized financial data, delivering detailed reports that helped identify root causes and improvement opportunities to streamline financial workflows. Key contributions: Optimized financial processes by reducing processing delays. Improved decision-making by providing actionable insights from complex data. Facilitated access to key financial data through clear, interactive dashboards that simplified delay analysis. This experience strengthened my skills in data science, database management (SQL, PostgreSQL), and Python programming, while also enhancing my understanding of public budget management, with a strong focus on accuracy and transparency in financial operations.

As part of the Budget and Procurement Division of the Province of Assa-Zag, I contributed to improving the public budget management process by using the Integrated Expenditure Management System (GID). This helped reduce administrative processing times and improve the accuracy of financial forecasting. Key responsibilities: Created detailed financial reports to monitor expenditures and support informed budget decisions. Integrated digital solutions to enhance transparency and interdepartmental coordination. Identified and proposed process improvements to optimize public financial management. This internship strengthened my understanding of public budgeting procedures, while also developing my analytical skills and my ability to collaborate in a multidisciplinary administrative environment.
