Introducing myself

Well, guys, I'm starting to write my first text in English.
I want to start by talking a little about myself: I'm Brazilian, single, trained in computer science, with graduate degrees in Web Development. However, I'm currently working in finance.
In the coming days, I will begin a course of game development for mobile platforms, an area that I want to invest in, and have my own business.
In my spare time, I like to surf the internet, read, listen to music, date and of course, sleep!
A few days ago I resumed working out, but it is not getting any easier, giving up sloth, mainly because here in Brazil, in the period from March to September is autumn / winter.
In the summer, which runs from December to March, we received many tourists who love visiting our beaches.
But Brazil is not just made of beaches. There are wonderful places such as mountains, rivers, forests, and finally, beautiful cities like Curitiba, Pocos de Caldas, Caldas Novas, Pantanal.  These are beautiful examples of interesting places to visit.
Parallel to this, I will continue to teach Portuguese for willing foreigners, here the portal.
Please do correct this humble text and correct whatever is necessary so that I can learn better.

[Your English is quite good for being a second language.]
