    *** Over 14 years experience developing mobile apps! *** What do many years of experience provide? A deeper understanding of client needs. Time to develop an established work ethic, a high level of professionalism and a sense of pride in your work. Time to develop philosophical understandings regarding UI design, programming concepts, communication style, approaches to testing, and more. I've worked as a consultant, independent publisher, and employee at a development agency. Prior to that, I received a BS in Computer Science from the University of California at Santa Barbara. I have ample experience creating apps from scratch and updating existing projects. My Upwork Portfolio includes only a subset of the iPhone/iPad/Apple Watch apps I have worked on. Please let me know if you would like to see the complete list! Apps developed in Swift and ObjectiveC. Let's talk - I'd love to see how I can help you with your project!

    I have been working professionally as an iOS Developer for over 9 years now. Through those years I have become advanced in developing full feature apps in both Objective-C and swift. Many of the apps I have worked on are very high profile with names you would recognize. Although I can easily develop all aspects of an iOS app from the networking layer to the front end, I am particularly good at mobile analytics and front end development. I am by far strongest in iOS development, but I also am well versed in a variety of other frameworks and languages. These include: Wordpress Ruby on Rails PHP JQuery AngularJS. As a final note, I was a creative person before I became a developer. As such, I have an eye for design. I find that most clients appreciate this.

    🔥 I am a 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. Check below for just a few of the apps I have worked on! My clients include: 📍 Apple 📍 Time Warner Cable 📍 DaVita 📍 Experian 📍 Charter Communications ⭐ What I can bring to your project ✅ Top-notch experience on all iOS platforms ✅ Extensive experience working with large Swift and Objective-C code bases. ✅ Expert understanding of software architecture ✅ Ability to quickly diagnose bugs and provide fixes that meet your timeline. ✅ 24/7 clear communication: you will always be aware of the project status ✅ Someone who cares about helping you succeed and bringing value to your business ⭐ Why you should choose me ✅ Client Reviews: I focus on providing value to all of my clients and earning their trust and praise. ✅ Over-Delivering: this is core to my work as a freelancer.

    As a curious kid, I had a desire to know how all things (especially gadgets) worked. When the iPhone was first released in 2007, I was determined. I began by jailbreaking to understand how iOS worked, and I started developing iOS applications soon after. So yes, I know what life was like before ARC :P In addition to freelance work, I've worked at a couple of startups, founded my own mobile application development company, and worked for a few larger corporations including Google. My experience of over ten years has helped me become proficient at mobile application development at a large scale.

    * 16 years doing all aspects of iOS development * Experienced tech lead, manager, and mentor I have been developing mobile apps since the original Palm Pilot, and shipped my first iOS app in 2008 as an independent developer. My main focus has been iOS ever since and I have many successful apps of my own on the app store. Recently I have worked full time for other companies, helping them bring great apps to the market. As an engineer I stay focused on the product, priorities, and schedule. A simple solution that meets those goals is better than a complex solution that is late and buggy.
