The Things I Do For A Living <- if it's a title, capitalize!

I don't want this to sounds like a resume, but I will try to simply explain what I do for a living.

I havestudied Industrial Electronics, and I have beengraduated, but I have only worked for a year in that field. After that I later got an opportunity to do software development, and I have been doing that for a living ever since. I learned the basics of computer programming when I was studying Industrial Electronics, but I learned a lot more using free resources found on the Internet and with a lot of practice.

That's it! Currently, I'm a software developer working remotely from home for an Australian company. I'm very happy with this lifestyle, which allows me to spend time with my wife and do other things that are more important.

It's nice when your work gives you time to do things you enjoy.

Great English, by the way.

Just tweaked things here and there to make it sound more natural.

Good luck with everything!

The things I do for a living

I don't want this to sounds like a resume, but I will try to simply explain what I do for a living.

I have studied Industrial Electronics, and I have been graduated. (This sentence would sound better like so: "I studied Industrial Electronics in (college or wherever you learned it)." It's implied that you already graduated unless you say that you "are studying.) But I have just worked for 1 one (spell out numbers 1-9) year in that field. After that, I got an opportunity to do software development, and from then, I have been doing that for a living. I learned the basics from of computer programming when I was studying Industrial Electronics, but I learned a lot with from free resources found on the Internet and with a lot of practice.

That's it! Currently, I'm a software developer working remotely from home for an Australian company. I'm very happy with this lifestyle (one word), which (see comment below) allows me to spare time with my wife and doing other stuff that are more important.

For the yellow highlighted portion: "That" and "which" can be used somewhat interchangeably, although with different grammatical implications. "Which" is always preceded by a comma (like in your sentence). If that sentence had a that, then in would be "I'm very happy with this lifestyle that allows me..." I felt that "which" worked better with the flow of the sentence, so I kept the comma and replaced the "that."

Overall, great job! Just a few small errors here and there. Also, just a reminder that the phrase is "earn a living" (with the "a"). Let me know if you have any questions!
