MCU applications

Having 10+ years working experience in both Cortex-M(FreeRTOS) and Cortex-A(embedded linux).
Having rich experience in sensors integration in MCU for IoT purpose with record proof. Design/implement/maintain highly density application in single MCU, including BLE, WIFI, SDIO, SPI, I2C, LED and GPIO interrupt.
Enthusiastic in new technologies and skills. So far, focus on voice control(AVS/ASK/Google assistant) and edge computing(greengrass)  as personal study.
I DON'T care about MANUFACTURE and PRODUCTION, but I DO really care about product itself - does it useful? what technologies inside? how it interact with user?
It's easy to build things by maker but what's the next?
Most of creators just focus on perfect HW/SW, but real use cases are more important than that.
If you CAN NOT design a useful product, that is, you just create a ART at most.
Let's flip the world!
