    🔥 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. My focus is on giving everything and more. ✅ Responsiveness: being extremely responsive and keeping all lines of communication readily open. ✅ Resilience: For any issue that my clients face, I work through it until I find a solution. ✅ Kindness: Treating everyone with respect, understanding all situations with empathy, and genuinely wanting to improve my client's situations. 🏆 Reviews and feedback from clients The client reviews below are just a few quotes that describe the quality of work and value that you can expect from working with me. ⭐⭐⭐⭐⭐ "You're awesome!

    In my past life, I worked as Automation Program Manager for a large company (Market Cap $14B+), designing and managing VBA and Python-based tools, ultimately saving the company over $4M / year in increased efficiency. As I built more software automations, I watched more peoples' jobs vaporize in thin air... Eventually, I couldn't take it anymore. I didn't want my software skills to be used lining shareholders' pockets, while my co-workers lost their jobs. Then I realized: Rather than automating jobs away, I could free up small business owners to do what they're passionate about, instead. And so, here we are! This feels like a much better way to put good out into the world. I like to take on projects which excite me. I have over 15 years of web/software development experience under my belt, and love bringing that to the table to help people create new, awesome tools.

    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.

    Currently working as a game designer and developer my skill set focuses mostly on programming but often I find that on the projects I work on I end up taking on a lot of the tasks. There are four games under my belt with another three currently in development right now. One is contract work for a game studio and the others are personal projects as I try to expand and push my talents. I have worked on UI, VFX, and pixel art as well but most of my experience is in game mechanics, systems, and level design with all the programming associated with that. C# and C++ are my most commonly used languages with some time spent in Java-script as the platform for the contract work is in the Android/IOS space. I learn quickly and will do a good job, that I guarantee.

    I'm a visual artist and can work fluidly across the digital landscape. I love making new logos, designing characters, illustration, comic art, and animation. Whatever your project is, chances are good that I have experience doing something like that. When I'm not making art, I'm either sharpening my skills or making more art. I would be honored to help bring your idea to life.
