I used to work in embedded software too. At the risk of sounding arrogant, it is my experience that embedded devs learn the web stack a lot faster & more thoroughly than vice versa. So should you at any point be interested in switching to web/mobile tech then be sure to get in touch.

And, totally unrelated, when I did embedded software, by far the coolest job I had was at a hardware startup. We were 9 people in a room making a lithography machine (a machine that makes chips) that could compete with the market leader's 20 year old junk. Said old junk was getting, well, old and broken, so we were trying to fill that demand gap.

I think at least half the team was working well outside their usual skillset at any point in time. It was super frustrating for people who considered themselves specialists and awesome for the rest. I learned a lot there about what a workplace where generalists thrive looks like.
