Hello,
I got an email saying that you are inviting me to bid on this project. I am a senior embedded developer with over 5 years of experience in embedded systems(C/C++). If you are interested in hiring me, please contact me and after that I can make a detail analysis of your project and if I project is simpler than I think it is I will reduce my bid. Also duration of the project will change if project is simpler.
Best regards,
ZMI
