• Published 4 production-grade Swift packages (10 libraries, 118+ commits, 500+ repository clones) on Swift Package Index, distilling nine years of shipped iOS work into reusable infrastructure and already in use across in-house apps. • RouteKit, a routing framework for scene-based UIKit/SwiftUI apps covering scene lifecycle, deep linking, and state restoration, so apps can go beyond single-window architectures. • AuthSessionKit (sign-in, token refresh, biometric gating, observable auth state) and BiometricAuthKit (Face ID, Touch ID, and Optic ID via LocalAuthentication), a Swift 6 strict-concurrency-safe library with fully Sendable types and a protocol-based interface module for testability.

• Founding engineer and iOS lead at a US neobank — owned the iOS platform from first commit through core banking rails and AI features. • Delivered mobile banking rails moving millions in ACH, wires and deposits. • Delivered one of the first production Tap-to-Pay on iPhone implementations, putting users among the first globally to accept contactless payments. • Architected the app into modular Swift packages — cutting build times ~40% and letting features ship and scale independently. • Harmony, a real-time conversational assistant over OpenAI's API and WebRTC — answering live questions on tax status, amounts owed and set-aside balances against the user's actual account data. • Document scanner on Apple's Vision APIs — edge detection, perspective correction, capture. • Vision-based check OCR, extracting routing numbers, account numbers and issuer from photographed paper checks. • Trained a Core ML model as a v2 of the OCR pipeline, extracting full check detail on device. 40% faster and 30% more accurate than v1. • Stripe-based in-app payments and subscription billing. • The real-time data layer keeping balances, transactions and invoice state live across sessions. • In-house keyboard framework extending UIKit for real-time validation and custom interaction. • Built a rule-based validation package for PCI-sensitive input — SSNs, birthdays, routing and account numbers.

• Led iOS across three consumer media products as Lead iOS Developer. • Integrated my own KVSTPAudioSDK with Spotify's iOS SDK and Lofelt's haptic engine — tapping PCM buffers via then-public streaming APIs to drive frequency-mapped haptic feedback, years before Apple shipped the equivalent. • Synchronized listening system where one user hosts a station and others join a shared playback stream, kept in step across devices. • Camera-flash pulse detection — extracting a heart-rate signal from frame-by-frame color variation, no external sensor. • Improved memory and battery draw through a UI refactor, and cut playback asset size. • Architected the Firebase auth, storage and API layer underneath all three products.
