What I'm looking for

I'm open to remote and contract work, as well as relocation within Europe, and can work across EU or US time zones.

At Walmart Global Tech, I build and maintain AR virtual try-on features for the Walmart app, extending eyewear try-on to earrings, rings, and shoes. I also built a camera-based face measurement scanner for prescription eyewear fitting, used across Walmart's optical centers.

I own iOS product features end to end, from SwiftUI and UIKit screens to GraphQL integrations, analytics, and testing. Before Walmart, I built and maintained a security-sensitive banking app at GLOBUS IT, and I’ve also built and shipped an independent AI health product across iOS, Android, and Python.
