ECU programming interpreter on ESP32

we have a project where we have to download a script file (that would be run by an interpreter written within ESP32) and a json file (that would contain the data that would be downloaded into the ECU (Electronic control unit)). once these 2 files are stored in the SD card, the interpreter would have to run the script and download the content of JSON file to ECU.

Candidate having extensive experience in ESP32 IDF programming, CAN communication, SD card file processing, only may apply.
