Hi,
I have 4 years of Python/Django coding experience.
I think I can do the backend and the async number crunching job in python.
I'm not good at website design though...if you have a design in mind , or a picture or example of how you want to look like , then I can work with that.
Depending on how complicated that is, I will update my bid accordingly.
For the backend part , I can do it in 1-2 days.
The frontend might take more depending on what needs to be done.
Let me know if I can help,
Thanks,
Bogdan
