Growing up, I was tech support for family and friends of family and also my own friends. I eventually worked as a PC technician for a few years and now work as a software developer. I have a very keen eye for how bad UI/UX is for most devices, computers and software because of it and it's been a huge help in my work in the same way, but it's also been quite infuriating when I see decisions being made that prioritize KPIs like sale and click through rates that intentionally make the UX worse.
