Hola, I am an embedded system engineer designing IoT systems. I have accomplished a tracking project with SIMCOM sim808 and Sim700 chips. I am glad to show my previous works as a reference to the project. I have designed a system has more than 500 sim modems. I have samples of PCB designed by myself. I am also strongly experienced in PCB design of such systems. Since I am a newbie to Spanish, it would be great to have an english description of the project. Also, you are more than welcome to negotiate for time and cost if we agreed on the design. Regards, Furkan Sönmez Embedded System Engineer
