Hi!
I've been actively working with python for about 5 years now.
I used pyramid for mostly of my web applications, but webapp2 should be no problem: the docs seems nice. Should you hire me I will invest some time (at my expenses) studying it.
If you fell unsure of my capability, before you hire me, let me build a sample for you. Maybe a simple mail processor?
Regarding the projects you mentioned, are they already started or should they be build from scratch? Could you elaborate more on them? Please, let me know what is your business too.
Hope we can work together.
Regards,
Laércio.
