I am a full stack developer who loves to also work on electronics on the side sometimes, and while I love all the amazing cool stuff we can build nowadays with cheap and powerful MCUs like esp8266, esp32,
as a full stack developer getting started in embedded 4 years back I found that building and sharing what you have built is a lot lot harder than what I was used to as a web, android, ios developer.
To solve those problems and to make it easier for developers to get started building and sharing their IoT creations I built prismos.dev over 4 years on the side,
think of Prism OS as Android "ecosystem" (OS + SDK + Play Store) for embedded platforms, I go into details about this at https://prismos.dev/the-goal
While I have been able to build an MVP that I am getting started sharing with others now,
I would love to partner up with someone who has experience building and taking electronics and embedded products to launch,
I think something like Prism OS can change the IoT projects are built and can make it much much simpler for devs to get into the field, 10x better that the current state of things.
