I’ve spent two years building iOS for a digital banking platform — payments, transfers, card management, account flows, Google Maps integration for branch/ATM discovery with custom dynamic marker clustering. Before that, another year on a second fintech product. That’s three years of fintech iOS.

I know the bar these products require: zero tolerance for crashes, strict security standards, complex multi-step flows that still feel seamless to the user. I’ve worked on all of it — auth flows, transaction history, push notifications via APNs, third-party payment SDK integrations, performance profiling and memory leak elimination under real production load. On the architecture side, I led a full redesign of a large module on a high-traffic app — built a business case, got stakeholder approval, and shipped in two weeks. I’m comfortable owning features end-to-end, not just executing tickets.

My stack is modern Swift — UIKit, SwiftUI, RxSwift, Combine, Swift Concurrency. I’ve led a UIKit-to-SwiftUI migration on a production app, and I have solid experience with Realm, CoreData, Fastlane, and the full App Store release pipeline.
