Hi , I am experienced developer in web-development , I have done full email client in php , c# with auto-discoverer email settings for i-map and pop with different protocols, also work with Gmail, Outlook, Zoho apis i can show demo even.
Your requirement is exactly as my skill set right now ;)
Also i can give you faster web-development with vue js framework so we can concentrate on our functionality then website design, and still getting current standards of beautiful web site design.
I will enjoy to work and show with you about my knowledge gain in last year in email api implementation.
My Bit is not conform , but we will conform it after getting project details.
Be sure that development will be faster and price will be reasonable, as i like to keep me updated with current web trends.
