At Similarweb, I analyzed algorithm pipelines and large-scale data to identify performance anomalies, trends, and inefficiencies. I also developed automated data validation tools using PySpark and the ChatGPT API.

For my Technion capstone, I developed a PyTorch deep learning model to score aortic valve calcification from echocardiography video data. I evaluated five model architectures and reframed the task as predictive risk modeling.
