My March 2019 resume: resume
My old academic page at University of Toronto is here
It has many PDF notes where I work out in meticulous detail a lot of results on Brownian motion, Hamiltonian mechanics, and spectral theory among other topics (including the most detailed proof online of the Trotter product formula in quantum field theory, and detailed notes working out the construction of the p-adic numbers and the adeles from the point of view of Pontryagin duality). There are also historical vignettes on the history of mathematics.
