Freelancing Opportunities for Firmware Engineers

I’ve been exploring ways to branch out into freelancing as a firmware engineer, but I’m curious how others have made it work. What kinds of projects have you found that fit well with freelance arrangements? Do you typically work on embedded systems, IoT devices, or something else entirely? I’d love to hear how you balance client expectations with the technical demands of firmware development. Any tips on finding reliable clients or setting up contracts would be really helpful too.
