iOS Developer · Swift · SwiftUI · AI Integration · 8+ Years Senior iOS developer with 8+ years of experience building production-grade apps for the Apple ecosystem — from architecture through App Store submission. Most recently shipped Notae, a solo-built AI-powered notes app integrating OpenAI Whisper and Anthropic Claude for voice transcription and image scanning, with CloudKit sync and StoreKit 2 subscriptions. Core stack: Swift · SwiftUI · UIKit · Combine · GRDB · CloudKit · StoreKit 2 · Firebase · CoreBluetooth · AVFoundation Strong on clean architecture (MVVM, SOLID), async/await concurrency, and integrating AI/ML APIs into real products. I write maintainable code, cover it with tests, and care about the details that make apps feel right. Open to long-term collaboration on ambitious iOS products.
