Career wise I find myself in a similar position. Roles in my niche skill set are largely offshore or contract positions now. I don’t like the idea of management. I love doing what I do… fixing bugs, investigating complex problems, not talking to people for days!!
I have been debating trainer or tester roles. There is also Scrum master as a possibility but I think that would be too regimented for me, there doesn’t seem to be much scope to adapt the scrum model for different situations - at least the way my employer does it!
Just some ideas, I don’t have much good advice as I’m spinning my wheels without a clear direction at the moment.
Search term “mini usb2 to usbc” on amazon UK came back with a good list… brands easyult and nfhk. No clue how good they are or if they would be available in EU/CH.
