What I'm looking for

I seek a hands‑on iOS lead/staff role where I can drive architecture, deliver scalable Swift/SwiftUI apps, mentor engineers, and improve product stability and payments.

I am an experienced iOS Lead and Staff Engineer with 8+ years building production iOS apps using Swift, SwiftUI, Objective-C and Cocoa Touch, and designing architectures from scratch. I deliver performant apps with protocol‑oriented design, SOLID principles, deep‑linking, analytics, payments (Stripe, Coinbase), and fast API handling.

I have led mobile features across travel, banking, fintech and startup products, resolving memory/performance issues, implementing multi‑language support, SDK integrations, and test‑driven development. I focus on clean, testable code, reusable private libraries, and measurable business improvements through analytics and stability work.
