ABOUT
Thoughtful products.
Native to iOS.
I’m Tim, a Senior iOS Engineer based in Mesa, Arizona. I’ve spent 9+ years building native Swift experiences, from creative tools at Adobe Lightroom to Places by Raya.
Outside of work, I’m building Mainichi, an AI-powered Japanese tutor designed around a personalized learning path. The entire experience is AI-backed to personalize the lesson path. It’s currently in internal TestFlight.
