What I'm looking for

I'm available immediately and open to relocation or remote work. I'm looking to build reliable native iOS products, own features end to end, modernize architecture, and contribute through technical leadership, mentoring, and cross-functional delivery.

I've delivered native iOS features for SNB NEO at Saudi National Bank, including card top-ups, recurring payments, limits, transfers, and multi-owner business-account journeys. I also migrated 10+ production screens from UIKit to SwiftUI and resolved a currency-conversion precision issue the day it was reported.

At CME Offshore, I built checkout, delivery, loyalty, browsing, analytics, and Quick Action Bar features for Dollar General, alongside social features for Vama such as feeds, subscriptions, real-time sockets, and push notifications. I improved reliability by eliminating memory leaks and redundant network requests, and received the 2024 Initiative of the Year award.

I've led feature delivery, architecture decisions, mentoring, code reviews, and releases across fintech and education products. I build maintainable iOS applications with Swift, SwiftUI, UIKit, MVVM, Clean Architecture, reactive programming, and a focus on performance and production reliability.
