Hi,
Could you share with me more details about the project do you want to build in arduino and node mcu? I have advanced knowledge in C and C++ software development for Arduino, NodeMCU ESP8266, ESP32 and ARM microcontrollers. In addition, I have worked previously in projects for IoT, IoMT and digital signal processing applications using various communication protocols such as: SPI, I2C, USB, UART, MQTT, RS232 and ModBUS. Always with excellent results.
Please contact me to discuss the details of your proyect. Bugs resolving cost are included in my bid amount.
Looking foward to work with you.
Best regards,
Javier Inojosa.
