a SIM900 project for rraduconstantin

Hello, I am a certified EE engineer with more than 6 years of experience designing building and testing electronic devices. I work as a r&d engineer in a lab, and in my spare time I freelance. I can help you with every aspect of your product. Do you have any constraints regarding size and parts to use? Do you want just to connect the two or also programming the device? Depending on what you want, the bid is negotiable. If you have any questions please contact me. Thank you.
