Though I need your detail specifications about the task, supposed the task doesn't exceed your project budget. Specify the works please.
1. Related Experience
I'm a 12-year-experience software engineer, especially pretty well both in PHP and Java/JSP programming with some real-world projects of course not in books. I can send you my CV, after accepted. Got BS/MS degree in Computer Science from the best university in South Korea.
2. Completeness
Writing clean and refined codes is most important part of building a software, through the testing/debugging task, I'll make the codes very carefully to make it just like as the one you used in WP plugin. I've trained well about this, while working at Intel where the codes should be perfect so that it could be solid & fixed on the chip.
