# Mentoring (Ad-hoc) with Wez Furlong

> For folks that don't want to or are otherwise unable to book via Patreon or Ko-Fi, this is a paid single hour of time where you can pick my brain about something. I have 25 years of tech industry experience with very broad and deep exposure to Systems Software Engineering at both a low level and at scale, as well as mentoring experience to help others grow in their career at a FAANG. Provided it can fit within the 1 hour time slot, I'm happy to talk about pretty much anything that is within my experience, and even stuff that is potentially a bit outside of it. See https://wezfurlong.org/mentoring/ for more information.
