Ritesh Pakala

ML Engineer (iOS/Swift spec)

I build intelligent mobile experiences at the intersection of AI and craftsmanship. From computer vision at Polarr to AI prototyping at Apple, I bring products to life with Swift, SwiftUI, and on-device machine learning. Currently focused on decentralized AI, native platform engineering, and making interfaces feel effortless.
