I'm ecommerce developer from almost 10 years.
I've worked with a lot of platform and now i'm studing Magento. I'm new in Magento and i've never deployed a Magento commerce yet.
Welcome to the world of Magento!
Magento is a big learning curve and initially you may face many challenges. Once you are into it you'll be in love with Magento.
My recommendation is to start looking into the http://devdocs.magento.com/.
