iOS & Apple Platform Development
Expertise in building and shipping 20+ production apps across iOS, iPadOS, macOS, watchOS, and visionOS using Swift 6 and SwiftUI, covering the full product lifecycle from architecture to App Store release.
On-Device AI & Machine Learning
Deep knowledge of Apple Foundation Models, Core ML, SpeechAnalyzer/WhisperKit, @Generable structured generation, local LLM deployment with Ollama, model quantization and inference pipelines, and GPT API integration, achieving sub-10ms inference on Apple Silicon.
Offline-First Architecture & CloudKit Sync
Proficiency in designing production-grade offline-first data layers using SwiftData, Core Data, and CloudKit, including conflict resolution, schema migration, CRDT/event-sourcing sync patterns, and role-based multi-user sync.
Swift & SwiftUI Frameworks
Strong command of Swift, SwiftUI, UIKit, Combine, Swift Concurrency (async/await, actors, Swift 6 strict concurrency), SwiftData, Core Data, App Intents, and WidgetKit.
CI/CD & Tooling
Experience setting up custom CI/CD pipelines using GitHub Actions, XCTest, Xcode Instruments profiling, custom release pipelines, Git, and App Store / Mac App Store submission and review processes.
Cross-Platform & Backend Development
Familiarity with TypeScript, React, Next.js, Python (Pandas, NumPy, scikit-learn), Flask, REST APIs, Firebase, VS Code Extension API, CLI tooling, and Linux/Unix administration.
Apple Ecosystem APIs
Hands-on experience with iOS, iPadOS, macOS, watchOS, visionOS, CloudKit, HealthKit, WatchConnectivity, MultipeerConnectivity, AVFoundation, VideoToolbox, StoreKit 2, Background Tasks, and Push Notifications.
Open Source Developer Tools
Author of open-source tools including Devscope (language-agnostic code-intelligence CLI and GitHub Action), SwiftUI CrossPreview (VS Code extension for live SwiftUI preview), and Xcode Doctor & SwiftUI Templates (macOS Xcode-config diagnostic tool and production SwiftUI architecture starters).
