    ----------------- "Who dares wins -- My Heart Is In The Work" ------------------ Hello Greetings , An new idea, I will be going to read on your description and through this course, feeling super interest in your project. Of course, I have the expert experience in development of social apps such great as dating app or E-commerce app , photo sharing app and so on. In particular, at the mobile company I have developed the decade of apps depending on consumers' requirements, so think that we can also establish a successful Co-operation for both of us. As I work with excellent designers and web guys together, no any obstacle during developing. The important factor is that we should be on same page for safe contract, based on high trust of each other, In technical side, that we should have unique opinion for beautiful design, smooth usage sensor and reliable quality guarantee. For this, can you provide app details and corresponding mock up? Finally you will get the best result in the shortest time with the 100% satisfaction degree and reasonable budget. Hopefully discussing the project with you soon... Please do not hesitate with your questions.

    China - Tests: 6 - Portfolio: 7

    "Faster is cool. Faster is in fashion. Faster is the talk." - That's my notion. I have over 8 years of experience developing native iOS applications in Xcode. I am comfortable with all aspects of mobile application development (application code, database backends, RESTful APIs, testing/debugging, and submission to App Store). I submitted 30+ apps in the App Store and knowledge of Apple Review and Human Interface Guidelines. I started my work with Mac OS X development when Apple came out with iPhone SDK.. since then iOS has been my world and my pride. I have worked on a wide variety of complex projects that include social media, financial for loan, mortgage, Parse.com, chatting, business and productivity applications. I was also leading the team to test(manual/funcational/stress test) the applications. Also, I have worked few Android applications and I am always open to exploring and creating new and awesome stuff. I feel mobile apps give me a way to show off my creativity and enjoy my work. So, if you want really creative complex apps that are architecturally strong.. I am the Guy!! As an experienced developer of both iOS and Android mobile apps, I have the skills and experience to create your app quickly and accurately. I am offering a FREE 30 minute consultation before you hire your app coder. With my extensive experience I can give you the most efficient design for your app. You won't regret giving me a try. --- Wang --- ( --- PS : Hiring a coder is a difficult decision. You want to hire someone who is not just a "part timer". Coders come and go with the wind, and you want someone who will be available for years to come. You may have just a simple app now, but as time goes on you can count on me to be there and help you if you want to upgrade or make updates to your app. While the other coders are out of business, I will be there for you to rely on. I pride myself in my availability. I will respond to EVERY email or message you send me. I am dedicated to excellent service. I am very fluent in English. Many of my clients speak English and I am to understand your request easily, and respond to you in easy to understand English. I make sure there are no confusion or misunderstandings. I will always restate your request back to you to ensure no mistakes are made. I have many references and invite you to request their email addresses to ask them about their experience with me. Many I have had several year ongoing relationships with and they always come back to me for their next project. Thanks for your consideration )
