What I'm looking for

I'm looking to own iOS features end to end in a remote, distributed Agile team, building scalable and accessible Swift applications while collaborating closely with product managers and designers.

I've built and shipped native Swift applications for C6 Bank, Santander, AktiaDuetto, and Empiricus Research, delivering features used at banking scale. At C6 Bank, I led a cashback feature serving 30M clients with 100% crash-free performance and shipped 48+ App Store releases.

I work end to end across Swift, UIKit, SwiftUI, REST APIs, architecture, accessibility, and CI/CD. I've also introduced GitHub Copilot into a production workflow, improving development-process efficiency by 25%.
