I’m a senior iOS developer with 6+ years of experience building and shipping production apps on the App Store, with a strong focus on payments, security, and real-time user experiences. I work end-to-end—from clean MVVM architecture and performance optimization to CI/CD, release quality, and post-launch monitoring—always partnering closely with product, design, and backend teams in agile, remote-first environments. Most recently I’ve been developing iOS features for a high-traffic e-commerce platform used by millions of users, handling secure payment flows with Apple Pay, Tap/GoSell, OTP/JWT authentication, and encrypted handling of sensitive data. Previously, I worked on an iOS delivery/product role for an app agency and multiple client products including healthcare e-prescribing and finance marketplace experiences, emphasizing secure API communication, reliable offline-first design, and analytics-driven improvements.
