I build secure, scalable mobile products and platforms across Android and iOS. I'm a Principal / Staff-level Mobile Engineer with 10+ years of experience designing and delivering enterprise-grade applications across cybersecurity, digital banking, video streaming, IoT, and developer platforms. My focus is where mobile architecture, security, performance, and engineering leadership intersect. What I do best • Mobile architecture & system design • Android & iOS native development • Kotlin, Swift, Jetpack Compose & SwiftUI • Secure mobile engineering — OWASP, STRIDE, Keystore & Secure Enclave • SDK and platform development • Performance optimization and reliability engineering • CI/CD, automation and engineering quality • Technical leadership, architecture reviews and mentoring • AI-assisted engineering and product development Selected impact • Reduced mobile security vulnerability footprint by 40% and cold-start latency by 28% at CyberArk. • Reduced password-reset failures by 35% for a large-scale digital banking application. • Reduced client-reported playback issues by 45% through Android SDK and ExoPlayer improvements. • Reduced application crash rate by 32% and dashboard load times by 40% through performance engineering. I enjoy solving complex engineering problems, designing systems that are secure by default, and helping teams raise their technical standards. I'm open to Staff / Principal Mobile Engineering, Mobile Architecture, and Technical Leadership opportunities where I can own architecture, drive technical excellence, and deliver meaningful business impact. If you're building challenging mobile products or platforms, let's connect.
