Hi Sir/Madam,
Hope to work with you on your project. I'm Android expert developer, having solid Android internal/framework/system knowledge. And I work very fast doing Android Java development, and also so fast at C/C++/JNI. I hope we can establish long term relationship, thus I can work as you requested any time available. I have similar SIP experiences, please check my profile and reviews, see if you want to work with me.
Please discard the budget and time frame in the moment, wish to change that after discussion.
Sincerely,
Duzy Chan
