Hi Sir,
I have to say that this is a very interesting project.
I am Nemanja, graduated computer scientist from Belgrade, specialized in backend engineering using PHP/Python and similar.
The reason I would like to work on this project is that this is something that I am looking for a years, I need something cool like this and I am more than capable to finish this project for you since my knowledge is very advanced.
I already have an idea how would I do this, especially because I would use NoSQL/MondoDB for faster JSON documented queries you need here because you need to harvest and check all that emails as faster as you can.
If you are interested, you can contact me and we can discuss more about this job, its very interesting.
I know that the price is a little high but I appreciate my work, time and my knowledge, and I take the job serious until it's finished.
Hopefully we will find a touch,
Best,
Nemanja
