I'm currently working on my graduate project and I have some free time. Python is my main Programming language and I have done many projects for my company and university in it. I'm familiar with lot of modules and programming patterns. I can finish your task in 7 days without a problem.
If you could give me 2 example codes (ARM and HEX) I would provide you more information about required days and payment, days will be probably less then 5 but I need some examples to verify it.
I have to say that I'm new on Freelancer so I haven't passed any of the exams yet. The same applies to my work rating. But this will be updated soon. ;)
Best regards, Tomislav
