Hello YourMarketCo,
I read your requirement proposal for "Need a Mercado Libre enginner or developer expert / Necesito un desarrollador o ingeniero experto Mercado Libre " carefully and
I am working from almost 10 years in HTML, MySQL, PHP, Software Architecture, Website Design and recently completed few projects which are almost same as yours.
I can do this within your budget too $15 - $25 USD / hour
Thanks
Mmadi
