buttons up/down for Arduino pro mini

Hi. I am an experienced Embedded System Developer. I have more than 5 years of experience in Embedded C programming. Furthermore, I am writing code with explaining comments. So, next developer, or you can understand what I did on this project. It is not a limit, but I am mostly working with these microcontrollers and development boards; 1. STM32F1/F2/F3/F4 (STM32Cube IDE) 2. PIC12, PIC16, PIC18 (MPLAB X IDE, MicroC PRO for PIC) 3. ATmega, ATtiny (Microchip Studio) 4. ESP32 (ESP-IDF or Arduino) 5. Arduino I hope you will find me suitable for this project. Best regards.
