I have 13 years of professional experience, and I work in a small company (15 people). Apart from one or two weekly meetings, I mostly just work on stuff independently. I'm the solo developer for a number of projects ranging from embedded microcontrollers to distributed backend systems. There's very little handholding; it's more like requirements come in, and results come out.

I have been part of some social circles before but they were always centered around a common activity like a game, and once that activity went away, so did those connections.

As I started working on side hustles, it occurred to me that not having any kind of social network (not even social media accounts) may have added an additional level of difficulty.

I am still working on the side hustles, though.
