Hi,
How are you? I have extensive experience in working with the nature of work you have shown.
Have done several project based on Arduino, server connectivity and data logging with different protocols. As I work for product architect, I would be able to provide all suggestions as well which includes less burden at BOM. Please consider my bid and negotiate as I would not like to lose opportunity to work on this project.
I am working on several other projects, other then in freelancer, so please don't just consider my current projects.
With Regards,
Abhishek Dwivedi
