Freelance Coregraphics developer in Littleton, United States

Senior iOS Developer with experience since 2009

Senior iOS Developer with industry experience since 2009. I have worked on dozens of mobile applications and continue to strive for quality in everything I create. I help companies create quality products in the beginning, or turn their already created application into one, that will last the test of time so it doesn’t need to be completely rewritten in a few months. Unlike other developers, I have experience from initial idea, to design, through implementation, and deployment, so I can predict potential problems before they happen to reduce costs. A little more about me, I’ve launched several dozen complex iOS apps. Collectively, they have grown to many millions of active users. My clients include Apple, Time Warner Cable, DaVita, Experian, Charter Communications, and many more. Check b...

iOS Developer with over 40 apps in 5.5 years. Get some help for free.

I began writing iOS apps professionally in the late days of iOS 2. Since then I've helped to bring over 40 high-quality apps to the App Store for clients in a wide range of industries. I specialize in helping companies turn complex desktop software into intuitive, fast, and great looking mobile apps. I also lead a team of developers and designers where we take amazing products from our clients and help turn them into incredible mobile apps. Why am I helping for free? Easy: I was self-taught and know how hard it is to find good people to answer questions. Knowledge should be free, even if manpower for implementing it isn't. I'll get you an answer so you can complete your project and move on to the next challenge. Periodically I also help teach "Let's Learn iOS" workshops for intere...

Freelance Coregraphics developer in Kalispell, United States

iOS Developer

I'm an iOS developer with a serious obsession with efficiency. No matter what it is, there's a better way to do anything, and I'm always in search of it. I am proficient in both Objective-C and Swift. Although iOS is definitely my focus and the platform on which I'm most proficient, I love learning new things and consider it a necessity for my own happiness. I have experience working with Java, JavaScript, Node.js and I've also done some work in Python. I have a Bachelor's degree in music production and engineering which has given me plenty of experience with project management. In my free time I love the outdoors especially when I can combine it with my love for travel. I'm also obsessed with fly fishing.
