Dear sir,
My name is Xiao Ming and I'm writing with regard to my desire for your job.
Your job really caught my eyes because my experience and expertise are perfect match for your job.
I'm a global lead mobile app developer who is expert at creating the iPhone and Android applications with Regular Education and Formal Training by IBM.
From 2007, I have been working as an independent mobile developer because I've got a great impression from mobile.
With the technical background and enthusiasm for mobile, I could achieve the solid knowledge of the iOS & Android platforms and extensive frameworks for 5 years.
Also, I learned to follow the International Standards for Quality Assurance and I'm aiming at building the highest quality apps more competitive than others in the market.
I'm looking forward to hearing you soon.
Best regards.
Xiao
