Hey there, my name is Zachary and I'm a computer science engineer, I totally understand your project and I can do it. I know exactly the steps to follow because I already did the same in multiple IoT Hackathon.
I don't have reviews for the moment and that probably scare you, but it doesn't mean I'm not competent, I'm just new to freelancer.com, If you hire me NOW, I will "IMMEDIATELY" start working on your project.
My pricing is certainly not the cheapest, but you are literally buying quality, the paradigm behind the code needs to be flexible to handle evolution and more subscriptions, that why I'm more qualified than the other because this is literally what I do for a living, think and solve problem that still didn't happen.
I'm not an amateur copying and pasting generic messages on projects like most of the people on the website, I only respond the projects where I'm sure to overperform. You don't need to wait anymore to find your freelancer because you already found it! Shoot me a message, I will love to discuss some details and the technology you want me to use.
Sincelry,
Get The Engineer
