Working as an embedded systems engineer in the fields of Automotive and IoT for the past 7+ years, I can tell you with confidence that it is a unique journey. After finishing my electrical engineering bachelor's, I had a goal of honing the craft of embedded software engineering. 2 master's degrees and multiple awesome projects later, and now I'm looking for the next chapter in my journey.
