Hello,
I'm a software engineer with over 4 years experience in the industry. I have extensive experience working on C#, C++, Python, C and PHP. I am confident that my skills would be well sufficient for the task you have at hand. In addition, as evident from this proposal, I possess good command over the English language and can polish the English section of your blog with ease.
Hoping to discuss the details of this project with you over private message,
George
