1,400+ students across 21 course offerings — databases, database system technology, software engineering, programming on the web, over a decade period. Led the department's migration from IBM DB2 to PostgreSQL: platform evaluation, rewriting every course material, retraining instructors, carrying students through a change none of them chose. Introduced XQuery into the curriculum from my own M.Sc. research, with assignments on real public datasets. Nominated for the U of T Scarborough Teaching Award, 2007.
