My work has been celebrated on stage at Apple’s WWDC, featured in the App Store and Google Play, and even won an Emmy! 🏆 I'm an expert marketer-storyteller weaving brand into the entire go-to-market strategy. Your brand is the emotional bedrock of your company and it has the power to move people. A strong brand-centric campaign will captivate your customers so that when they are ready to buy, they are compelled to come to you. Here's what clients have to say: ⭐️⭐️⭐️⭐️⭐️ "Lindsay has a great ability to take extremely rough ideas and turn them into well-executed designs -- she's a masterful creative." For 15+ years I have crafted next level campaigns for clients small and large from startups to global ad agencies. I've worked with Warner Media, March Madness Live, PGA TOUR, Vail Resorts, JetBlue Airways, Major League Soccer, Accenture, Better Homes and Gardens, Tango, and many more clients with brand-success stories. I love crafting captivating brand-forward marketing strategies that ignite client's excitement, thrill their customers, and deliver real-world results. Whether you've got an existing identity or need an overhaul I'd love to make your brand work for you!

Once those wireframes’ flows are approved, the app’s screens are designed, in part by taking the visual identity established in Platform Branding and using it as a jumping off point to establish the app’s look and feel. High-fidelity mocks are passed from our designers to engineers who code these frontend screens into existence. At the same time, backend engineers are building the behind-the-scenes pipes and engines that make your platform tick and operate effectively. Testing is heavily integrated into our Product Development process. We test the stability of the code as well as its ability to scale with platform growth. Testing is also incorporated to account for various phone devices and environments. Support and maintenance help is also available for clients once products are released.

Hey there, I’m Jonathan. I’m a software engineer on a high-performing tech team at one of America’s largest communication companies, building digital experiences for tens of millions of consumers. Our customers rate our app at 4.5 stars (approaching 200,000 reviews), higher than any of our competitors. Our team is leading the charge to turn an old corporate company into a modern tech powerhouse. Revolutionizing a 100,000 person organization is no small task and can’t be accomplished overnight, but we’re confident that it can be done, and that we’re the team to do it. I have experience in Business Intelligence, creating custom analytics solutions to collect billions of events to power strategic reports and insight to my enterprise’s executive team, including the C suite. My specialty is C# and Xamarin, with a strong iOS streak. I’ve built backend web services in ASP.NET, and first wet my feet in tech building WordPress and Angular websites when I was in high school. I have experience in Angular, Node, and vanilla JS development. I’m an architectural purist, I believe in doing things right the first time. I don’t take the cheap route. I’m strong in theoretical and practical object orientation. Separation of concerns, inversion of control, a single source of truth, abstraction, and a clean service stack are very important to me. I’m vocal about the way I think a solution should be built. I’m always interested in hearing about new projects, so please hit me up if you think we might be able to work together. My LinkedIn URL is jmccormick583.

Bachelor of Science, Computer Science, Colorado State University. I have long been passionate with software and game development, and spent many years learning web development on my own time. I can mock up a website in just a day, and have excellent graphical and writing skills, allowing me to design software and websites efficiently. I am currently working on my own original game with Unreal Engine, modeling assets in Blender. I also develop plugins for a Minecraft server, which will become public in the future. I am looking for work related to my interests only, so that I can provide quality results, gain more experience in the job environment, and have something tangible to show off to future employers. So, I am not interested in touching up a wordpress website or other small things that can be done in an afternoon.
