I am an avid daily (and nightly) user of wikipedia, and I feel like I will never be able to repay this community for everything it gave to me during the past 19 years or so. Anyways, after years and years of postponing, on 24 February 2018 I decided finally to register and I made my first little modification.

Since then, I have been editing some pages from time to time, mostly about mathematics (differential geometry) and mathematicians, as well as stuff I read/watched/bumped into, both in the English and the Italian wikipedia. Unfortunately, I have never committed too much time in it, but doing so is my constant new year resolution.

Since February 2021 I am more active, doing at least a couple of (non-minor) edits almost every week.
