I'm a Staff Software Engineer who builds in public. Right now, I'm shipping API Canvas—an iOS app for API testing—and documenting everything I learn along the way, from choosing Swift over React Native to navigating the quirks of native development as a longtime web developer. With over 10 years of industry experience, I've worked across the full stack—React, TypeScript, backend services, AI integrations, and now native iOS with Swift. My focus is building tools that feel intuitive and native, whether through desktop apps, web services, or mobile experiences. My strength is moving fast and shipping products people actually want to use. Following my journey? I write about what I'm learning at erickumlin.com. Always happy to connect with fellow builders, developers making the leap to mobile, or anyone curious about software and side projects.
