Beginning of my career

By on July 21, 2011 in Personal

After long days I’m writing this post. Though my blog is very popular for facebook related tutorials, but this is not anything related to facebook or php. This is about me and beginning of my career.

I think every programmer should learn different languages and work in different platforms. You can ask me why? If you work on PHP backend development for 5 years, you will become an experienced guy and will earn better income.

So why you’ll invest your time for other language and other platform?
Because it will give you a good taste of programming and you’ll enjoy yourself. I’m not telling you to leave PHP development and move to other platform, I’m just telling you to make some extra time from your regular job and work in different platform or technology.
