Wei Yew Teoh developed and enhanced the ROKT/rokt-ux-helper-ios repository over seven months, focusing on robust event data modeling, UI architecture, and CI/CD automation. He introduced Swift-based structures for event ingestion with deduplication, refactored UI components to MVVM using SwiftUI and Combine, and optimized performance through memory management and reactive updates. Wei migrated CI pipelines from Buildkite to GitHub Actions, consolidating Xcode testing and streamlining release workflows. His work improved code maintainability, test coverage, and deployment reliability, while also strengthening documentation and data integrity. Throughout, he demonstrated expertise in Swift, CI/CD, and modern iOS development practices.

January 2025: Delivered a CI/CD overhaul for ROKT/rokt-ux-helper-ios, migrating from Buildkite to GitHub Actions with composite actions for Xcode version management and consolidated Xcode testing across Swift versions/toolchains. Introduced DebounceCollector to batch events and refactored EventProcessor, improving throughput and reducing duplicate processing. Updated tests for Swift 6 compatibility (ViewInspector 0.10.0) and aligned SwiftLint; performed minor UI extension cleanups to stabilize the UI layer. These changes reduce CI maintenance, accelerate feedback cycles, and position the project for easier Xcode updates and scalable testing in future releases.

December 2024 performance snapshot for ROKT/rokt-ux-helper-ios. Key features delivered include UI redraw optimization via LazyPublished with ViewModel refactors and OuterLayerComponent styleState binding. Major bugs fixed cover memory management and lifecycle stability for EventProcessor; removal of retain cycles involving layoutState/layoutLoader; and prevention of duplicate image fetch by simplifying load conditions. Overall impact: smoother user experience, fewer missed events, reduced network load, and improved maintainability. Technologies demonstrated: Swift ARC memory management, property wrappers (LazyPublished), ViewModel architecture refinements, and targeted testing. This contributed to increased reliability, lower CPU/memory spikes during UI updates, and reduced data fetch overhead, delivering clear business value through performance and stability improvements.
