Hello,
I am a Senior Python Developer. I made a lot of crawlers for different projects (including projects regarding news, music, games, movies, software, voucher, tickets, etc.). Some of these projects I've done on freelancer (and vworker/rentacoder) - as you can see on my profile. About experience - I started working in Python in 2008. If this is OK with you, we can discuss details.
Regards,
Nick
