Hi, I'm Mick
I've been building software since 2011, specializing in iOS development. I've worked extensively with Objective-C, Swift, and React Native, and have dabbled in web development with Node, React, and Next.js. I enjoy projects to improve DX and love building and optimizing custom CI/CD pipelines.
Based in Fort Myers, Florida, and I enjoy travel, finance, and all things technology. Oh, and I chronically install day-one iOS betas on my personal devices!
