About

🚀 Senior iOS Engineer | 7+ YOE | Scalable App Architect | Swift | SwiftUI | MVVM-C | Mentorship | Performance Optimization I’m a passionate mobile engineer with over 7 years of experience delivering scalable, production-grade iOS applications. From architecting clean modular systems to mentoring teams and driving end-to-end delivery, I thrive at the intersection of clean code, product vision, and technical leadership. At RingCentral, I lead the development of critical mobile experiences, mentor junior devs, and own release management.

I specialize in: - Native iOS (Swift, SwiftUI, RxSwift, Realm, Firebase) - Architecture patterns (MVVM-C, MVC, modular architecture) - CI/CD (Jenkins, automated test pipelines) - Cross-functional collaboration, mentoring, and team building Now exploring Senior and Staff-level opportunities at global product companies to solve large-scale technical challenges and build impactful products.
