I come from a traditional full-stack engineering background (web frontend + backend) and recently founded a smart toy company[1], the first product built on ESP32-S3. I took a few weeks for me to get comfortable writing firmware (although there is another more experienced engineer doing the primary work and electrical).
I'm really excited for Espressif (the chip maker) to roll out newer versions of their microcontrollers on RISC-V. I would love to see a renaissance of inexpensive personal devices.
