In the past, I was course responsible lecturer for Graph Theory (1MA170, at BSc-level) at Uppsala Universitet during the winter terms 2020, 2021, 2022.
I was also frequently a teaching assistant holding exercise classes for courses on linear algebra, single-variable calculus, multivariate calculus, and probability and statistics. This includes both courses for mathematics students, as well as students in other programs, typically engineering or computer science.
