No, Mohammed, wages are low enough here without working for free. Anyway, if one of us did help someone, then we'd get hundreds of messages from other people asking us to do the same thing. Why not advertise it as a rewrite job in the $5-10 range? It would be worth the investment.

However, since I'm more or less on holiday, I'll have a little look anyway and give him a few hints.
But it doesn't matter.
You are not promoting your English language skills. You do programming and you don't need to improve your English in order to do that. When you interview with clients they will know that you are not a native English speaker and most of them will not care.
Just have a native English speaking friend rewrite your profile text, or hire somebody to do it. It's not that big a deal.
All punctuation goes directly after the last letter, with a space after it e.g.
Hi Dave, how are you?
I am fine, thanks.
Also, you don't have to have each assertion as a seperate sentence, I'll do one for you:
I am Md Hannan, I am a professional Web Designer and Web Application Developer who has been working in this field for 5 years.
Finally, why are you using quotation marks (""), who exactly are you quoting?
The biggest violation I see are the inclusion of links.
As Preston mentioned, if you're not into the Writing category then the grammar would not be your primary concern. I suggest you put those links in the cover letter of your application. But don't just copy-paste your whole portfolio. That would earn you bad rep as far as the algorithm is concerned.
Write a short but sweet cover letter showcasing the links in your portfolio. Everyone has their style so make sure it feels natural to read.
