Dear client. I understand that, you want a customize distro with eGalax Touch Drivers and a minimal Raspberry Pi OS with Node.js pre-installed.
I have over 3 years of experience in embedded system/ raspberry pi. And I have worked on many distro including Arch linux which is minimal and rolling update based distro. I have done driver integration for WiFi device. It will not be a simple task as it is consisted of several small tasks, but it is manageable in time.
If you think I can complete this job, please feel free to contact me here on freelancer.
Thank you!
