Hi! I am good with Magento, and while I am not US-based, I can talk over the phone - my English is fluent, my accent is very similar to say West Coast accent (CA, OR, WA) accent mostly. I was in the US personally, and I am a professional. You can give me the hours you need me to talk eventually - when necessary - and then even if it's night time here in Romania, I will make sure to wake up when you want to be on call with me. Let me know, thank you!
