What an amazing career and good life choices (I guess). I'm also Electrical Engineer, but my career looks boring compare to this. Progression is hard, never reach an official Senior level after more than 10 years and 2 compagnies.
I had also a growing passion for Bitcoin and to some extent finance around it but fail to pivot my career into it and regret not having try harder.

Still not late, and at least I have my happy family and that's stay the biggest achievement of my life.
