Build me a Arduino Device with GSM and SD card Caching

I have made projects like this and have prior experience in the modules which are to be used in the projects. I will complete this project on time as said. So please provide us with this project.

Hi Sir, I am very expert engineer and developer. I can do your project in instant and have capability to do it for you. Lets talk to us on this project. Regards. Ahmed

WE HAVE THE HARDWARE (SIM900) AND EXPERTISE TO COMPLETE THIS PROJECT.......!!!! 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'm an electronic engineer with more than 5 years of experience in Arduino related programming and embedded systems designing. I've decided to apply for this project because I have good knowledge and experience related to MQTT and using GSM modules. I have completed many other projects using these technologies, so I'm confident about completing this project successfully. Looking forward to hearing back from you. Thank you Anusha

yes buddy,,me here to accomplish the task, u will feel brotherhood,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

Hi, i am an embedded engineer, i have used MQTT in projects, and worked with the protocol modbus over RS232 and RS485 physical interfaces. Well the arduino have an RS232 interface (the serial interface of arduino is 232), but to use the RS485 we will need a chip such as the MAX485. I have worked on projects using GSM/GPRS module, such as M10 Quectel and SIM900, SIM808 of the Simcom , i am very familiar with using AT Command if needed, and above that, i have a fair amount of knowledge in the embedded electronic field, i am pretty sure i can help you achieve your project with success. Best Regards.

Hello sir, I am final year student of electrical engineering i have been working with circuits and devices more than 3 years I work locally for companies Now i want to build up my future here I will give you my best and hopefully you will find me best among all others Tell me your projects detail so we can start work on it Hope to hear good from your side Thanks

Hello, I have 3 years of experience in internet of things. I am able to control appliances via internet using cloud or Bluetooth. Also able to work on raspberry Pi, Arduino, esp and other hardware programming. kindly share more details to proceed further. thanks
