About

Professional summary

I am a lead iOS engineer with more than 10 years of experience building architecture for complex, multi-module mobile apps and platform SDKs used at scale.

I have led engineering efforts at companies like Fox, Pluto TV, Chewy, Thrive Market, Beauty Counter, LegalZoom, Fonality, Age of Learning, and Final Draft, with a strong focus on Swift, SwiftUI, UIKit, Objective-C, and modern iOS architecture.

My work has centered on modularization, scalability, performance tuning, release engineering, and testing strategy. I have built reusable SDKs, caching systems, networking layers, player platforms, and internal tooling that improved reliability and developer velocity.

I am deeply hands-on and enjoy solving hard technical problems, especially around concurrency, app performance, memory usage, and debugging with Instruments and LLDB. I also have extensive experience with CI/CD, code review, and cross-functional collaboration.

In recent years, I have also incorporated AI-assisted development into my workflow, including Claude and GPT pair-programming, AI-augmented code review, and MCP server integrations. I use these tools to improve architecture, refactoring, and test generation while maintaining engineering rigor.

I am comfortable leading teams, setting coding standards, mentoring engineers, and partnering with product, backend, security, and QA stakeholders to ship high-quality mobile experiences.

Career history

Software Engineer 3, iOS Chewy

Architected a WebView eager-loading system across native surfaces, cutting Deals and Cart load times by 90% for millions of users.

Designed a forward-caching LRU cache with TTL as a reusable foundation for native surfaces, and built Blur and Contrast reusable libraries plus an Image Carousel architecture using SwiftUI and UIKit.

Diagnosed and fixed a GPU over-instantiation thermal issue with Instruments, established a repeatable performance and power debugging playbook, and built an internal debug console for validating analytics pipelines. Owned on-call responsibilities and resolved critical production issues while mentoring junior and co-op engineers.

Senior / Lead iOS Engineer Pluto TV (Paramount)

Set coding standards and drove CI/CD, XCTest coverage with mocks, snapshot testing, and code review across the iOS team.

Architected platform capabilities used by feature teams, including an Optimizely feature-flag harness with V1/V2 routing, dynamic authentication with tvOS second-screen QR login, and reusable component systems.

Adopted async/await and MainActor isolation for networking, led a cross-platform Appium automation framework spanning iOS and Android, and coordinated releases with security and backend partners across time zones.

Lead iOS Engineer, Video Fox Corporation

Built a player SDK consumed by FOX Now, FOX Nation, and FOX Sports using protocol-oriented design and dependency injection.

Architected a large-scale MVVM + Combine refactor of high-traffic video apps and migrated data fetching to GraphQL with Apollo, improving maintainability and performance.

Reduced video load times by 40% through profiling and implemented Picture-in-Picture and Chromecast/AirPlay. Integrated Segment, CONVIVA, and MUX for quality-of-service observability and evolved build/release infrastructure on Bitrise, Fastlane, Jenkins, and GitHub.

Senior iOS Engineer Thrive Market

Built a networking layer over REST and WebSockets with multi-threaded request batching using DispatchGroup and GCD.

Implemented high-performance pagination and integrated Optimizely, Segment, and Mixpanel to support experimentation and analytics.

Senior iOS Engineer Beauty Counter

Architected a Swift SDK wrapping MagTek Bluetooth card readers via Core Bluetooth and BLE for a production point-of-sale app.

Authored shared libraries BCKit and BCNetworking and enforced quality with SwiftLint, Danger, Quick/Nimble, and Bitrise CI.

Senior iOS Engineer LegalZoom

Architected LegalZoom's first mobile app and modularized the codebase using CocoaPods and submodules.

Built an OAuth2 API layer and Core Data persistence to support a scalable mobile foundation.

Software Engineer Fonality

Built real-time VoIP functionality using C++ pjsip with Swift and Objective-C bridging.

Worked on cross-language integration and mobile communication features.

Senior iOS Engineer Age of Learning

Built a Core Data caching pipeline and optimized memory and threading with Instruments.

Focused on performance, stability, and efficient data handling for mobile experiences.

Software Engineer Final Draft & Online Resources

Delivered cross-platform software using C++, Objective-C, STL, Boost, and SQL.

Contributed to application features and shared code across platforms.
