Nice to meet you, sir.
I have read your job description very carefully, again and again.
Having thought carefully, I conclude that I can complete your job perfectly, so I bid.
In my opinion, I can wrap up your project within a day.
Well, talking about my ability, I learned how to program in C/C++ and Java language since I was 15.
And now I'm 25.
I'm quite young but I've 10+ years of experience with programming.
I think young developers are more needed than old one because we, youths, have a great potential and passion.
I can stay up all night, and can work for more than 20 hours a day. (of course if it's needed)
First, I have great experience of Windows Desktop App using C/C++/C#/Java.
Also, I have 7+ years of experience with Website development with HTML, CSS, JavaScript, JQuery, PHP, MySQL, JSP, ...
I have confidence in mobile apps too.
Last but not least, I also have a quite good skill in algorithm and datastructure (because I'm an amateur mathematician), data processing with MS Excel, etc.
Anything you want, I can satisfy you.
Anyway, seeing is believing. Please try to hire me.
You'll be satisfied with my work. I'll provide you best quality result and will keep the deadline as well - Best Quality & Shortest Period.
If you hire me, I'll do my best for you and for your job.
I could support you not only just now but also in the future, not only for this job but also for any kind of job. I'm prepared for anything.
Regard.
Looking forward to hearing from you soon.
