Josh Gilbert

Josh Gilbert

Yet Another Rockstar Developer

United States

I live and breathe information technology. I could type my own name before I could write it. I began writing software at seven years of age under my father's tutelage. I began working as an independent contractor in the field in my early teens and have remained entrenched in it since that time. With nearly two decades of professional and hobbyist experience in desktop, mobile, and web application development across a variety of platforms (iOS, Linux, OS X, and Windows, and more) as well as the personal management and discipline skills necessary to survive as an independent contractor for the majority of my life, I can bring just about any project to life. While my development philosophy is holistic, I have been known to obsess over what I consider critical details. To summarize: even while a chain is no stronger than its weakest link, the burden isn't always equally distributed. I would also offer a paraphrased thought from Antoine de Saint-Exupery: Perfection is achieved not when there is nothing else to add, but when there is nothing led to take away. As I had developed a wide range of skills outside of formal academics, I got a late start in college. Now I'm just another student trying to make ends meet as I labor toward a lifelong dream of establishing my own information technology firm. I am as committed to technology as any one person may get. In closing ... I love technology and I love working with technology ... it is both a hobby and a career. I am one of the few people who are lucky enough to have a strong passionate enjoyment of what they do, and I'm eager to put that passion to work for my clients and their projects.

Expert iOS App Developer with Financial, Social App experience, More

China - Tests: 6 - Portfolio: 6

"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,, 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 )
