Jorden
iOS Developer & CS Undergraduate
I turn ideas into working products through self-directed learning and hands-on problem-solving. Experienced in Swift & SwiftUI, AI integration with Google Gemini, and full-stack solutions powered by Firebase. Shipped Cashy+ — now live on the App Store.
What I do
Building things that live in pockets and run on silicon.
Native apps with Swift & SwiftUI — from home-screen widgets to App Store release. Focused on performance, polish, and great UX.
Embedding conversational AI into mobile and embedded products using Google Gemini, Whisper, and on-device ML inference.
Raspberry Pi robotics, 3D printing with a Bambu Lab X2D, and bridging the gap between software and the physical world.
Firebase Firestore, Authentication, Cloud Functions, and real-time sync — backend that scales without standing in the way of shipping.
Featured projects
Things I've designed, built, and shipped.
