At Okanagan College, I cleaned and structured research datasets with Python and SQL, contributing to four peer-reviewed publications accepted at IEEE SysCon 2025 and CCECE 2026.

On a financial data warehouse and ML forecasting project, I integrated more than five years of stock market data through automated ETL pipelines and developed a dashboard for forecasts.

I also built a four-page Power BI dashboard exploring Canadian population trends and designed a PostgreSQL database for a hospital wayfinding system at Interior Health.
