Hello, I uploaded an IoT related article sample in my portfolio. Just click on my profile here in Freelancer and download it.
I have worked as an SAP consultant before in IBM, where CAMSS (Cloud, Analytics, Mobile, Social & Security) solutions were constantly being applied. I'm a technology enthusiastic, and I've followed the topics that you mentioned in the description and the methodologies associated with them for multiple years.
My rate is 0.1$ per word, that gives us a 100$ quote for a 1000 word article. I still would like to know more in what you are looking for, how frequently do you need new articles , etc. I can deliver an average-length article within 2 days, depending on the schedule of course. Contact me if you'll like to discuss more information about the project, regards.
