I build reliable iOS banking platforms and lead SwiftUI migrations.

At Uzum Technologies, I lead iOS work for a B2B banking platform serving 15K+ daily active business users. I own transaction processing and trade operations, delivered remote Digital Onboarding, and built a SWIFT transfer module supporting migration to the SWIFT MX payment standard.

I led four iOS engineers through a full UIKit-to-SwiftUI migration using modular VIPER-based Clean Architecture. I maintain a 99.8% crash-free production rate through Firebase Crashlytics and proactive incident response, while improving API load time by 30% through networking refactoring and caching.

Previously, I improved mortgage application conversion by 15% at Moscow Credit Bank and built internal and customer-facing banking apps at XalqBank. I also developed investment tracking, telemedicine, and crypto portfolio applications as a freelance mobile developer.
