Oracle Labs
Automated schema generation for Oracle's Financial Crimes & Compliance systems, enhancing data processing. Fine-tuned 7B models to optimize schema and handle abbreviated column names. Created a framework to evaluate schema generation and data integration accuracy. Improved metadata consistency from 0.4 to 0.6, boosting data interpretability. Optimized output parsing for better data flow and results with 7B models.
Oracle Labs
Enhanced machine learning explainability for the AutoMLx project by optimizing LFI/GFI explainers, reducing their processing time by 80% and improving inference speed. Streamlined memory usage from 20GB to 4GB, lowering operational costs for explanation services. Achieved 83% code coverage to ensure reliability and maintainability of explainability features. Collaborated with cross-functional teams to deliver scalable, high-performance ML explainability solutions within AutoMLx
National University of Rabat
Engineered a deep learning model to predict RFID pricing by scraping specifications and market data. Deployed the solution on GCP using Docker for scalable performance and built a Django web application to streamline data collection and real-time model testing.
