Dear Sir
I’ve just read your job post description carefully line by line and I’m very interested in this job.
I’ve rich experience in development of iOS, Android and Web apps using hybrid app development techniques. I've developed many mobile apps with several kinds of services including payment apis, social networking, image processing, and media clouding.
I’ve been working like a dog full time over 70hours per week if I have tasks or job but bill only 6~7hours a day.
This is because it is more important to help somebody with my skill than to earn money.
I can work on you business timezone, so I'm always available to you.
As you know, I’m new to Upwork and haven’t work history here, but I will do my best to work to complete this project without relax until the project is done .
I think, I' m proficient in English, so we can communicate each other easily.
I’d like you to give me opportunity to work for you.
Best Regards
