I'm new to freelancer but please don't discount by bid because of my lack of ratings. I'm an expert with wordpress and have spent many hours with Paypal's API in managing membership subscriptions & sales for several non-profits.
I am a US-based developer, very experienced in wordpress, I write clean code and I stick to best practices (use of child themes, etc). I'm also available on skype during working hours. You're welcome to check my profile & portfolio for examples of my work. https://www.freelancer.com/u/HannahWebMonkey.html
Thanks for your time!
best,
Hannah
