Earlier quoted context omitted.
I am considering a career AND industry change, and I'm almost 40. Can you give me some general advice or pointers about career switching. I'm not entirely sure why I would think you might have a basis, just reaching out.
This is not an advice, but just a comment. I think many software engineers would KILL it if they worked for small mom and pop shops, or small practices. They could help turn many $500,000/year businesses into several times that revenue. Plus they would have WAY more autonomy then working at startups and tech companies, which in my opinion are just factories.
Immediate family concerns and other obligations (e.g. parental care) at a later stage in life may necessitate a more gradual shift through successive job transitions, rather than a sudden career change.
Technically, an "experienced hire" should be attempting to shift into careers that allow for maximum skill transferal, but this isn't always possible, and it certainly isn't easy.
