I will develop esp32 firmware with idf framework

If you plan to create a modern device, you in 99% cases need an MCU to control it. Having a well design PCB is a must but for sure not least requirement to success. You also need a solid, flexible and robust firmware (a "brain") that for modern applications play the most crucial value.

The ESP32 is a powerful and cheap platform for modern IoT devices and is used in various scenarios and applications. Wireless is everywhere, networks, WiFi, BLE, ZigBee, Meshes, other fresh cool stuff is all everywhere around.

I will build a firmware for you using an official framework from Espressif ESP-IDF, so you may rely on having a fully up-to-date, most feature full, production grade, modern solution (no 'Arduino'/'Platformio' dependency).

Describe your idea, provide some task definition and we together will estimate your particular project. I have lots of hardware at my disposal and usually debug and develop with real hardware involved in the process.

Feel free to negotiate, programming is a complex art. Lets rock!
