At Punch (MarketPulse), I own FinanceLib, an in-house iOS charting library built on SciChart for real-time financial charts in a 1M+ user trading product. I design reusable Swift and SwiftUI components and build chart infrastructure for continuously updating market data.

At VideoLAN, I shipped features upstream to VLC for iOS and contributed to the iOS/tvOS codebase through Google Summer of Code. I also designed, built, and shipped Mini Browse, a native macOS app, solo from concept through App Store release.
