We are looking for someone, who could write a custom firmware for common MicroSD card. We need a card with WORM (Write once, read many) functionality - any data written on the card can not be altered or deleted once written. It can not be possible to format the card. The data should be preserved even during firmware upgrade (or firmware upgrade can be disabled/forbidden). We would need a source codes for the firmware to be handed over to us.

Hello, I am Anthony from Sri lanka. I have 7 years of experience in the filed and I am very much interested in your project. Why you should hire me ? * As a full time freelancer I have my own PCB fabrication work shop and testing lab. So there is no problem doing live tests with you after the device has been developed. * My workshop is equipped with CNC machine, FDM 3D printer and DLP 3D printer. So there is no problem designing and printing plastic parts you required. Please contact me if you are interested. Thank you Anthony

Hi, I am very much interested in your project as I believe I have the expertise, knowledge, skills and tools to do your project. I am embedded software developer with more than 12 years of experience of professional embedded software development. Please take a look onto my profile to know more about me. I learnt that it is possible to write protect SD Card if we have direct acces to it. So I belive an embedded system would be a right choice to do that. Therefore I would like to know if you have any preference for embedded systems like Arduino, ESP32 or STM32 or something else or I ca choose myself? Regards, /Ibrahim
