I'm a professional Django developer and I worked with projects like this before. You mentioned that you are building a simple showcase utilizing time-series modeling, are you currently have an implementation and want to integrate it into Django or is this the task you need to get finished.
I love working with Django, I'm also holder of Udacity Nanodegree of Machine Learning and Deep Learning. I also worked with IoT projects before. Honestly, I'm proposing for this project because I want to work/study in Korea and I will apply for government scholarship this year(if they open). I'm the talent you're looking for, let's discuss the details!
