Sara Vaez

AI & Machine Learning Specialist | Finance & Data Science

Master's in Economics ยท AI/ML Practitioner Certificate (University of Waterloo)

I build machine learning solutions that solve real business problems โ€” from credit risk modeling to time series forecasting to natural language processing. My background bridges quantitative economics, finance operations, and applied AI, giving me a unique ability to translate complex business challenges into data-driven solutions.

Currently working in Finance at Seaspan ULC (Shipbuilding & Maritime), where I apply analytical and AI-driven approaches to operational and financial process improvement.
