I help founders and small teams rescue, ship, and automate software that is already close to the business. My strongest work is where product, engineering, and operations meet: - AI workflow and operations systems - iOS / React Native app rescue, TestFlight, and App Store release work - API, Stripe, backend, and cloud integrations - data/market-intelligence pipelines - technical audits before a full rebuild or handoff A few relevant examples: - Built and rebuilt mobile apps from scratch to release, including SwiftUI, React Native, Node.js, MongoDB, AWS EC2, and S3. - Rebuilt Parti's iOS app from a bloated Swift/Storyboard codebase into a faster SwiftUI app with a Node/Mongo/AWS backend. - Built Penkra, an operations automation cockpit using Electron, Next.js, TypeScript, Postgres, S3, Stripe, WhatsApp workflow concepts, and approval-gated agent workflows. - Migrated Zoom Bots to Zoom Apps using Objective-C during my Zoom software engineering internship. - Built and launched iOS apps, including App Store work, Stripe payments, testing, build automation, and backend integrations. I am a good fit if you need someone who can enter an existing system, find the real blockers, explain the tradeoffs clearly, and ship the practical next step without turning the project into a science experiment.

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.
