Hire the Best iOS Developers in California

Senior iOS engineer with 15 years of native iOS experience, currently at Meta (Facebook App iOS) where I own performance metrics across billions of daily active users. My work spans metric-driven performance investigations, regression root-cause analysis, on-call production engineering, and AI-agentic tooling that automates performance analysis at scale. Before Meta: Senior/Lead iOS engineer at Amazon/Ring (hardware-connected consumer product), Citizen (safety app, TCA/SwiftUI architecture migration), Woosh (audio messenger, built from scratch), DraftKings (SDK development), and multiple startup teams over 15 years. I also build independently: Sky107 (sky107.app) is a solo-built FAA Part 107 exam prep app I shipped end-to-end -- modular Swift Package architecture, SwiftUI + TCA, Swift 6.1 with modern concurrency, live on the App Store. Deep expertise in Swift (2018-present), Objective-C (2011-present), UIKit, SwiftUI, TCA, performance optimization, and architecture for large codebases. I take on consulting work selectively -- 0-to-1 builds, architecture modernization, and performance engineering for teams that need iOS done right.
