I design and ship Swift & SwiftUI features for high-traffic consumer apps — marketplaces, FinTech, and connected IoT — where the hard part isn't building, it's shipping into a live codebase without breaking the users who depend on it.
Designed and shipped semantic search and AI-generated listing-comparison summaries inside a live marketplace serving 15M+ monthly active users across four brands. Owned the UX for AI disclaimers and result states, with A/B-gated rollout via Amplitude experiments and feature flags.
Built universal-link routing and server-composed share images across Finn.no, Blocket, Dba and Tori, and promoted feature components into a shared, token-based design-system library reused across all four brands — enforcing WCAG 2.1 AA and VoiceOver accessibility throughout.
Owned the main dashboard and flagship feature of a connected air-quality app with real-time sensor rendering. Led a large CoreData refactor that unblocked WidgetKit extensions, and ran Instruments memory-profiling to sustain a 99%+ crash-free session rate.
Built secure, high-volume banking and payment apps for 300K+ users — P2P transfers and automated toll payments — with SSL pinning, payment-token encryption and biometric auth. Passed rigorous third-party penetration testing with no runtime vulnerabilities.
Optimized rendering pipelines for smooth video playback in a media-sharing app used by 10K+ active users, built pixel-perfect UIs with custom transitions, and decoupled large legacy components into clean, testable MVVM modules using Swift Package Manager.
